question for using MATLAB Compiler (mc) for Undefined function

I created a .m file that is used to generate subsystem for my simulink model. I want to use it in cmd, so that i compiled it by using

mcc -m myprogram.m

it generate a myprogram.exe file I run this file but it returns error

??? Undefined function or method 'open_system' for input arguments of type 'char'.

my program.m

function convert2subsys(sys)
  open_system(sys);
  blocks = find_system(sys, 'SearchDepth', 1);
  bh = [];
 % for i = 2:length(blocks)
    bh = [bh get_param(blocks{2}, 'handle')];
 % end
  Simulink.BlockDiagram.createSubSystem(bh);
end

Please help. I am using matlab 2010(a); btw, should i use the matlab coder rather then matlab compiler?

Hi,

the Simulink Products are not made for compiling:

http://www.mathworks.com/products/ineligible_programs/

Maybe consider calling MATLAB with the -r option in order to run you program from the cmd

[yizhan]

my batch file

win D:\Program Files\MATLAB\R2010a\bin\matlab.exe -nosplash -nodesktop -minimize

start matlab -nosplash -nodesktop -minimize matlab -r convert2subsys('new') -logfile c:\temp\logfile

i did write a batch file, but the matlab and simulink window will open. When i try to close it in .m file use "exit", it ask me if i want to save the new model. In case, i can not really auto close the model... is there anyway to do it?

Thank you ...

Maybe do a load_system instead of open_system and then do a save_system before calling close_system

[Kaustubha Govind]

You can use close_system with the save flag parameter:

close_system('mymodel', 0); % close without saving

(or)

close_system('mymodel', 1); % close after saving

This will prevent the save dialog from popping up.

Thank you guys, it works now. The simulink process is been done invisibly.

There is only one window opening... which is the "matlab command window" is there a way to close it? I mean in batch file.

I have tried taskkill, but is will prevent the matlab file running.
