I have the following Simulink model:
I have the following script:
Constant=43;
Constant1=43;
Constant2=43;
Constant3=43;
Constant4=43;
Constant5=43;
Constant6=43;
Constant7=43;
Constant10=43;
Constant11=43;
In1=[1,2,3];
In2=[4,5,6];
t_stop = 10;
T_s = t_stop/1000;
options = simset('solver', 'ode5', 'fixedstep', T_s);
sim('test_lau.slx',t_stop,options)
I want to display and eventually call the outputs Display, Display2 and Display3.
I tried changing the last line to:
[Display, Display2, Display3]=sim('test_lau.slx',t_stop,options)
But get the error:
Number of left-hand side arguments doesn't match block diagram. When specifying that root-level outports are to be returned individually, the number of left-hand side arguments must be 2 (for T,X) plus number of root-level outport blocks
Does anyone know how to extract those outputs from a script?
Thank you in advance for your help!
Thanks to #Ander Biguri and #Wolfie
The answer was using the block "to Worskpace" instead of the block "Display"

I have a custom function I have made, which requires two input arguments. This is the opening line of the function, clearly showing it needs just two input arugments:
function [file,frame,vertices,edges,faces,faceOrders,edgeOrders] = FOLD_reader(filename,rundocfolder)
The FOLD_reader function is called within another function (FEAfromFOLDVaryingStiffness), using the following line of code:
[~,frame,vertices,~,faces,~,~] = FOLD_reader(filename,rundocfolder);
To which matlab claims:
Not enough input arguments.
Error in FEAfromFOLDVaryingStiffness (line 12)
[~,frame,vertices,~,faces,~,~] = FOLD_reader(filename,rundocfolder);"
However, if I copy and paste the offending line into the command window, it works perfectly. The filename and rundocfolder variables are definitely defined in FEAFromFoldVaryingStiffness which calls FOLD_reader, as they are among the input arguments of the FEAFromFold(etc) function itself.
Has anyone had any experience with this seemingly bizzarre error? To me it makes no sense at all.
If it's a help here are the lines up to the error point inside FEAfromFOLDVaryingStiffness:
function [] = FEAfromFOLDVaryingStiffness(filename,meshsize,displacement,m,n,stiffnessvary,rundocfolder)
%Comments ommitted for brevity
[~,frame,vertices,~,faces,~,~] = FOLD_reader(filename,rundocfolder);
I'm an idiot, I called the FEAfromFOLDVaryingStiffness with one too few arguments, I'd left out m or n or something and so the last input variable (rundocfolder) was undefined, which showed up as an error with fold_reader inside the FEAfromFOLDVaryingStiffness function, instead of where the error actually was: the top level script.
I published the following code in Matlab, although the desired output was produces, but along with that it also generated an error while publishing. Any idea why?
%% Gaussian kernel function
% Some text
function t0 = kachra(Param)
t0 = Param;
end
Attached is the Published output.
Thanks
You need to specify an input to your function when publishing.
If you select Edit Publishing Options you see the following GUI:
Modify your expression here and then publish it in order for input arguments to be passed.
You need to configure custom settings to publish your code with output result.
[t0] = kachra(100); %the argument is of your choice.
add your command-line input argument manually here:
i had a code that c send back 1 number (mex)
the matlab code was
vMsg=unit32(Gateway_test_app(2))
now i added 1 more return value to Gateway_test_app(2) which is s STRING
what i need to do to get the two values back
i was thinking about something like this:
[vMsg,errMsg]=??????(Gateway_test_app(2))
what should i put in the ????? place?
thx for any help
johnny.
ps
using codegen and need not to get err when building
First call the function and store the two outputs, then run your extra function unit32 (what does it do, by the way?) on the first output only:
[vMsgOriginal, errMsg] = Gateway_test_app(2);
vMsg = unit32(vMsgOriginal);
This assumes that you don't want to process your new string output through your unit32 function.
I have written a macro for ImageJ/FIJI to deconvolve my confocal microscopy images and run the "3D Object Counter" plugin. The macro successfully runs all required commands and saves all required data in the specified places.
However, I have found that the 3D-OC autothreshold (as shown in the plugin dialog box) is to stringent resulting in objects being lost or divided.
To remedy this I would like to reduce the autothreshold by a predetermined function something similar to what was done here (from:How to get threshold value used by auto threshold Plugin) which resulted in this code:
setAutoThreshold();
getThreshold(lower,upper);
v=setThreshold(lower,upper*0.5);
run("3D Objects Counter", "threshold="v" slice=10 min.=400 max.=20971520 objects statistics summary");
The idea was to call the AutoThreshold values, modify them and set them to a variable. However when these lines are run the following error is returned:
Number or numeric function expected in line 3.
v=<setThreshold>(lower,upper*0.5);
And if the variable is inserted directly into the threshold key for run(3D-OC) the following msg is encountered:
Numeric value expected in run() function
Key:"threshold"
Value or variable name:"setThreshold(lower,upper*0.5"
Any suggestions or help on how to designate the 3D-OC threshold value as a variable as described would be greatly appreciated (as would any work arounds of course :) ).
Cheers
Edit: After testing Jan's response below (which works perfectly), it appears I need to call the threshold set by the 3D-OC plugin. Anyone know how to do this?
The getThreshold(lower, upper) function returns the lower and upper threshold levels in the provided variables. There is no need to assign any value to a new variable, and as you observed, setThreshold does not have any return value.
Instead, you can use the value(s) returned from getThreshold and use them as parameters in the run method (in the correct way, by string concatenation, see here):
setAutoThreshold();
getThreshold(lower, v);
run("3D Objects Counter", "threshold=" + v + " slice=10 min.=400 max.=20971520 objects statistics summary");
Alternatively, you can use &v in the second parameter to avoid string concatenation in the last line (see the documentation for the run() macro function):
run("3D Objects Counter", "threshold=&v slice=10 min.=400 max.=20971520 objects statistics summary");
You might have to use the lower instead of the upper threshold value, depending on whether you count bright or dark objects.
I've been looking throught the documentation, but can't seem to find the bit I want.
I have a for loop and I would like to be able to view every value in the for loop.
for example here is a part of my code:
for d = 1 : nb
%for loop performs blade by blade averaging and produces a column vector
for cc = navg : length(atbmat);
atb2 = (sum(atbmat((cc-(navg-1):cc),d)))/navg;
atbvec2(:,cc) = atb2;
end
%assigns column vector 'atbvec2' to the correct column of the matrix 'atbmat2'
atbmat2(d,1:length(atbvec2)) = atbvec2;
end
I would like to view every value of atb2. I'm a python user(new to MATLAB) and would normally use a simple print statement to find this.
I'm sure there is a way to do it, but I can't quite find how.
Thankyou in advance.
you can use disp in Matlab to print to the screen but you might want to use sprintf first to format it nicely. However for debugging you're better off using a break point and then inspect the variable in the workspace browser graphically. To me, this is one of Matlab's best features.
Have a look at the "Examine Values" section of this article
The simplest way to view it everywhere is to change this line:
atb2 = (sum(atbmat((cc-(navg-1):cc),d)))/navg;
Into this, without semicolon:
atb2 = (sum(atbmat((cc-(navg-1):cc),d)))/navg
That being said, given the nature of your calculation, you could get the information you need as well by simply storing every value of abt2 and observing them afterwards. This may be done in atbmat2 already?
If you want to look at each value at the time it happens, consider setting a breakpoint or conditional breakpoint after the line where abt2 is assigned.
