I use Matlab R2008a and I try to replace handmade C code with code generate from Simulink model.
I've reach a good result but in some file I've an unnecessary function , generated to initialize the data structure : _initialize().
Now, how can avoid the generation of this function?
More in general, is possible configure RTW so to generate only one *.c and only one *.h files (except rtwtypes.h)
Thanks for your suggestion
Below my configuartion :
MATLAB Version 7.6
Simulink Version 7.1
Real-Time Workshop Version 7.1
Real-Time Workshop Embedded Coder Version 5.1

please help with this problem
while i am trying to deploy a model into Arduino mega from my 2013a 32bit matlab i had this error.
( The corresponding 'Model name.tlc' file for the MATLAB S-function 'Model name' in block 'block name' must be located in the current working directory, ...)
i have looked in many websites and forums for solution but i couldn't find, maybe because i am not familiar with matlab much. but i guess the problem is with S-function. i noticed that it is easy to get tlc file if i use s-function builder. but the current model i am trying to deploy is {M-S-Function: User-definable block written using the MATLAB S-Function API...}
what shall i do?
after i used newer version of matlab and newer version of the support package i was able to generate automatically all the files including tlc file.
I'm using a MATLAB function block within a Simulink model. I build this model and run it on a dspace system with 1 kHz. To evaluate my experiment I need the data (20x20 double array) that is calculated in my MATLAB function block. Is it possible to export the data to the base workspace?
To read a variable from your system, the easiest way to do so is using ControlDesk. Create a project and download/start your experiment using ControlDesk, then it is automatically aware of the running application and can read the variable. You now have to configure a Measurement (or Capture in old versions) and export the results to MAT. You can find detailed instructions in the documentation from dSPACE, called HelpDesk.
Alternatively you can use the XIL-API or HIL-API to automate the above steps.
I use the R2013a version of matlab. I tried to follow the path,
syntheticDir = fullfile(toolboxdir('vision'), 'visiondemos','digits','synthetic');
handwrittenDir = fullfile(toolboxdir('vision'), 'visiondemos','digits','handwritten');
but there were no files named digits.
Also upon running,
trainingSet = imageSet(syntheticDir, 'recursive');
testSet = imageSet(handwrittenDir, 'recursive');
I got the following error : Undefined function 'imageSet' for input arguments of type 'char' .
I'm trying to attempt this example, http://www.mathworks.in/help/vision/examples/digit-classification-using-hog-features.html
Usually I would consult the release notes of the respective toolboxes to find out when a new function was introduced.
For the digit classification example mentioned, it uses imageSet a new feature in R2014b, as well as the extractHOGFeatures function introduced in R2013b. It also uses fitcecoc from the Statistics toolbox. This a new function in R2014b.
It would be nice if the documentation provided this information in easier way...
This example was added in R2013b. Generally, if you have an older version of MATLAB, you should use the documentation that came with it. The documentation on the web is for the current release, and so it will naturally contain new examples and functions not present in the older versions. However, if you click "Other Releases", you can see the archive of the documentation for the previous releases. This way you can easily check when a particular function or example was added.
I have been trying to find out how to deploy a Simulink model. There are possibilities and problems as well.
If I use Simulink Coder how can I find the generated code on my computer? Where is it saved as a file or package of files?
Can we deploy Simulink as .NET Assembly? If we can, where can I find a detailed documentation about it.
Is there any other way to use my Simulink model standalone?
Thank you for any effort.
By default all the code gets placed into a folder, in the current directory, called ModelName_CodeTarget, where ModelName is the name of your model and CodeTarget is the particular type of code you are generating. (This folder is created during the build process if it doesn't already exist.)
There is no mechanism for automatically generating a .Net assembly. Simulink Coder generates C code; what you do with it is then up to you (just as it would be with hand written code). Note that the process is fully customizable, so you could create your own build process to autmatically wrap the C code into an assembly (but it would be a very advanced maneuvre to do this).
There are a couple of Simulink Coder "targets" that generate standalone executable files. For instance, the GRT (Generic Real-Time) target generates a simple .exe file; the RSIM target (the Rapid Simulation Target) generates an exe where you can specify different .mat files that can be used to specify different model parameters for different simulation runs, and have the results of the different runs stored to different output .mat files.
Most of these questions are answered by looking at the early chapters of the Simulink Coder documentation.
It would be worth you taking some time to look at it to get a feel for how the code generation process works.
I have a simple model from simulink and I would like to generate code using the code generator in the simulink and then compile it using gcc into a .ELF object file. How can I proceed?
Thanks
You need the product called Simulink Coder (around matlab 2011b) or Real-time Workshop (for older matlab versions). Typing ver at the matlab command window will show what products and licences you have installed.
If Simulink Coder or RTW are installed, you use the menu Simulation->Configuration Parameters to set up the model for code generation.
If you have Embedded Coder you can set System Target File to ert.tlc, and this will produce a very concise main() routine to call your model code. Otherwise, use grt.tlc which produces a lot more bloat then ert, but is the only useful one available for on Windows.
There are a lot of options to go through and check - it really needs someone with a bit of experience to be present!
As you are requesting an ELF file, is this for an embedded system? If so, there is a lot more work to be done. If the target is not one of the already supported targets, then you need a target package, which will take either a lot of time and experience, or money to buy one.
Custom target development - a world of it's own:
