I am trying to get my feet wet in SimScript simulation.
I wrote a simple code contains a function that returns the its first parameter.
This is my code:
preamble
define Normal.fn as a double function
end
function Normal.fn (means, f)
define means, f as double variables
return (means)
end
main
let x = Normal.fn(2.1,3.1)
end
However, when I execute the project, I got an error message states:
The executable file MyProject.exe is missing
I build and rebuild the project many times, but I am still having this problem.
I noticed in my executable folder, the MyProject.exe has not been generated.
I don't know what is going on, I am new to this programming language.
Could you help please?
I found the solution myself,
It was a missing library in the simscript version 3, i check the simscript version 2 libraries through file system and I found it, it is the one named "IDebugC.c"

I've been trying to fix this for a couple days so any insight would be greatly appreciated. I am building a project with an ESP32 board and VSCode's esp-idf framework. I am having trouble getting access to an outside library's functions. For example, I have implemented an FFT-noise-filter program in c, and now i want to bring it into the esp-idf framework. I think it has something to do with my unfamiliarity with CMake, and I have tried all sorts of different "CMakeLists.txt", but not sure what it should look like. I've been through cmake tutorials, but I just can't figure it out. Here's my current 'CMakeLists' inside main folder
idf_component_register(SRCS "hello_world_main.c"
INCLUDE_DIRS ".")
I took an example project 'hello_world' from esp-idf's examples, and wrote my own code inside of the 'hello_world_main.c'. It is weird because in my "hello_world_main.c" the complier seems to know some data types such as 'FFTW_Complex', which are only found in the library I'm trying to use. However, when I call any functions like FFTW's 'malloc' from that same library, I get an error "undefined reference to fftw_malloc()"
excerpt from hello_world_main.c's 'app_main():
//complex: double[2] = {real_part,imag_part}
fftw_complex *in, *out; //no errors here for some reason
fftw_plan p;
//initialize the arrays-> "in" is an array of fftw_complex type (basically a pair of doubles)
//in is f (set of points we know) -> out is fhat (complex fourier coefficents) with magnitude and phase
in = (fftw_complex*) fftw_malloc(sizeof(fftw_complex) * N); //'undefined reference to fftw_malloc'
Error message:

`fftw_malloc'
so my question is, how can I get my main to recognize the function calls I am making?
Add your libcode.c to:
idf_component_register(SRCS "hello_world_main.c" “libcode.c”
INCLUDE_DIRS ".")
And add a reference to libcode.h:
#include “libcode.h”
Libcode is an artificial name, change it by the correct one and you could also add a directory if needed like “libcode/libcode.h”
Hope this answers your question; with more code it’s easier to understand your problem.
To check what the minimal component would look like, you can create one using idf.py create-component NAME. The component named NAME will be made, and you can check what is missing in your external library.
While deploying packages of Matlab code using Matlab 2015 I encountered the problem of gathering all required files from my repository to run a certain file or set of files. Matlab has a method for simplifying this process, matlab.codetools.requiredFilesAndProducts.
However, sometimes some files are missing in the repository (either because I got a package from someone else who was not that careful or because it was not checked in in the repository).
When running the code one would get of course an error:
Undefined function or variable 'XXX'.
However, this may take long to fix (running takes long, you would have to repeat for every missing file). Therefore I thought to use the function above. Unfortunately, it only lists existing files in the output (I tested this). Functions that are called from your code, but that are not present in the current path are omitted by matlab.codetools.requiredFilesAndProducts.
My problem: I would like to get a list of all files that are required by running a certain file but are not present in the current path so that I can find them and add them to my collection.
I know that this must be an iterative process because the missing files could themselves call other missing files and I know that there would be false positives, some of these items could be unknown variables instead, and I know that the missing files would only have a name, no path (of course).
My question: What is the easiest way to find a list of potentially missing files of my code in one go?
Please note that function depfun has been removed in recent versions of Matlab.
I have tried to read many documentations (especially http://blogs.mathworks.com/loren/2008/08/11/path-management-in-deployed-applications/ where the question is asked but not answered to) on compiled Matlab GUI but was unable to find an answer to my question.
I want to create a compiled GUI in Matlab (compiled with deploytool and that can run on a computer that does not have Matlab), where at some point, the user can specify his own matlab .m file (say for example : myProfile.m) and the Gui uses it later on (this last point is the tricky part).
myProfile.m is some simple function (it takes one argument and outputs one value) that can be located wherever the user wants, and that is totally user defined. I give here a simple example:
function [y] = myProfile(x)
y = x^2;
end
but it can be more complex.
In the Gui I ask the user the path to his profile function and I try to make it a function handle :
Button1 = uicontrol('String','Browse path to your Profile',...
'Position',[320 10 150 150],...
'Callback',#button1_Callback);
function [profileFunc] = button1_Callback(varargin)
[ProfileName,ProfilePath] = uigetfile({'*.m'},'Select your profile');
addpath(ProfilePath);
profileFunc = str2func(strcat('#',ProfileName));
% profileFunc will be used later on in the code
end
Of course, after compilation this code doesn't work, and I get the following error:
'C:\Users\...\myProfile.m' is not in the application's expanded CTF archives at
'C:\Users\...\mcrCache8.0\myGui'. This is typically caused by calls to ADDPATH ...
I know that using addpath in a Gui does not work when you compile the Gui. But if I don't add the path, the program can not find the user provided myProfile.m . So how can I solve this?
Thanks,
Sam
When viewing this from a licensing point it is very simple. Mathworks can not allow to deploy such code, you could easily deploy your own command line version of matlab which runs arbitriray code and does not require any license.
In my opinion there is only one way to go: Deploy m-code and ask the user to install matlab or octave.
Alternative:
If you deploy a jar, the JRE is already running. Concider using java script as the JRE already brings the script engine. Then the user would have to input java script.
I am trying to run Kevin Murphy's Bayes Net Toolbox in Octave and encountering some problems. It doesn't help that I'm a novice at Bayesian networks, Matlab and Octave.
This toolbox was originally written for Matlab. There is a large test file called test_BNT.m which runs through all the functionality in the toolbox. Most of the error messages relate to the difference between & and && in Matlab and Octave. This is easy to fix. However, I've now come across a new problem and I don't know what to do about it.
For instance, the qmr1.m script creates an instance of the pearl_inf_engine class, sets some of the member member variables and passes the instance of the class to another function. Later on, the member variables are accessed again in a different script (parallel_protocol.m). But when this happens, the following message appears:
error: invalid index for class
error: evaluating argument list element number 1
It seems that from one script to another, it has forgotten that the class has any member variables and gives the invalid index message when you try to access them.
Is this a common error with an easy solution? Is something wrong with the path or working directory? Maybe someone else has already converted the BNT to octave and knows what to do?
Edit
I was able to get past this error message. The trick was to read the installation instructions (haha) and run addpath(genpathKPM(<BNT base directory)). genpathKPM.m is a script includes in BNT which adds all the required directories to the path.
After doing this, run test_BNT.m and change & to && and | to || at each line where it gives a warning. This will clear up most of the errors.
However, I'm still unable to run mpe1.m, mp2.m, mildew1.m and some others. The new error message I'm stuck on is:
error: invalid empty index list
error: called from:
error: C:\FullBNT-1.0.7\bnt\BNT\inference\static\#var_elim_inf_engine\find_mpe
.m at line 63, column 5
on this line of code:
eval(['sCPT.T(', sargs, num2str(jj), ')=0;']);
If I can get all the scripts to work, I'll post an answer here with the steps I took to do it.
Edit 2
I was able to get past the problem in the previous edit. Replace
eval(['sCPT.T(', sargs, num2str(jj), ')=0;']);
with
eval(['sCPT.T(', sargs, sprintf('%d',jj), ')=0;']);
The next problem is identical. Just replace num2str in the same way.
This file was apparently contributed by a user of BNT, and not written by the original author. Using eval kind of a hack, I think. A better fix would be to just rewrite the code so it doesn't use eval at all.
There is one more error in draw_graph.m, which was apparently also an outside contribution to the project. I just commented out the call to that function since I'm not interested in drawing graphs right now. After doing this, and continuing to fix shortcircuit operators, all of the tests in test_BNT.m will run.
Still, I won't create an answer for this until I can get draw_graph.m to run, too.
As a significant amount of time has passed, and the answer to the core problem was provided in the question, I will post it here so it will not stay listed as unanswered:
tl;dr: Change a few operators, solve the remaining bugs specified below, and everything works except the drawing of graphs.

I am a student who is envolving in a research about robust visual tracking.
And these days ,I had met a problem in my study.
The teacher gave me a project of matlab code about the research, when I try to run this code, and the program error is as follows:
??? Attempt to execute SCRIPT mexLasso as a function:
F:\L1_Tracking_standard_car\mexLasso.m
Error in ==> L1Tracking_release at 95
c = mexLasso(Y(:,i), [A fixT], param);
Error in ==> demo at 46
tracking_res = L1Tracking_release( s_frames, sz_T, n_sample, init_pos,
res_path, fcdatapts);
When I go to the program tracking, I found that mexLasso function does not exist, Only get an empty mexLasso.m file and a mexLasso.mexw32 files.
My OS version is Windows 7 64bit,and the matlab is matlab 7.12.0 r2011a
Does anybody here knows the causes of my problem?
Anymore, I wonder if anybody knows who has the source code of the binary file mexLasso.mexw32.Because I thought that if I can get the source code of the file mexLasso.mexw32,then I could compile its 64 bit version myself.(I doubt that my os could not recognize the .mexw32 file.)
I hope my express clear enough to let you come to help me ,thanks a lot!
I think your analysis is basically correct - mexLasso is intended to be a MEX function, but MATLAB is finding only mexLasso.m which presumably contains help text. Unfortunately, the error you're getting isn't terribly helpful. As I see it, you have two options:
Obtain the source code for mexLasso and recompile on WIN64
Run the WIN32 version of MATLAB on your WIN64 machine
the function mexLasso comes from the SPAMS toolbox
http://www.di.ens.fr/willow/SPAMS/.
You can find the sources there and compile the mex file corresponding to your OS.
First, you need to find mexLasso.cpp file in http://spams-devel.gforge.inria.fr/downloads.html as Marial has already mentioned.
Then you can find and download the recent version of SPAMS.
A following stage is just to execute compile.m file on your MATLAB.
Finally you can find mexLasso.mexw64 in the build folder.
Good luck.
