I would like to generate the code via .m script from a simulink model.

Note : i am new to script , can u add the description in steps aswell

I have abc model and respective .m file to load all the parmeter .

Now i need to generate the code and publish in jenkins pipeline.

i need to run the run the script calling the matlab model and respective parameter files to generate the code.

I tried withthis .bat file calling the .m file in jenkins but its taking much time and code gen is also not happening.

%.bat file%

PATH=%MATLAB_HOME_2021%\bin;%PATH%

matlab.exe -nodesktop -nosplash -r "run('./abc.m');exit" -wait -logfile logfile

REM To remove the build folder created for matlab execution

:://RD /S /Q "slprj"

%.m file%

run('abc_StartUp.m');

warning('off','all')

%generate code

try

open_system('abc.slx')

rtwbuild('abc')

catch

end

end

clear;

**************************

Did my above file content is correct , can anyone support on this.

Hi Poornachandran,

Here I am assuming, "code generation not happening" as, there is no error and the BAT file is being executed indefinitely.

Based on this assumption, following are the few optimization I was able to identify in the M-script:

• Instead of "open_system" function you can use "load_system" to load the model, since "open_system" not only loads the model but also tries to open it. Using "load_system" may remove any unneccessary computation in MATLAB which is running with no desktop option.
• In the M-script, 'rtwbuild' function is used to generate the code, however, according to MATLAB documentation it is recommended to use 'slbuild' instead of 'rtwbuild' to generate the function.

To learn more about load_system, "rtwbuild" and its recommendation, please refer to the following documentation:

• rtwbuild's recommendation: https://www.mathworks.com/help/rtw/ref/rtwbuild.html
• load_system: https://www.mathworks.com/help/simulink/slref/load_system.html
