ERROR IN MATLAB CODER...

I´m using the MATLAB example Hello World for testing the MATLAB coder tool. (The simplest example in the MATLAB HELP), and the MATLAB give-me follow error report in the prompt window.

??? Attempted to access instrumentAndRunPos(0); index must be a positive integer or logical.

Error in ==> echodemo>formatError at 245 stackStart = max(iRet(iRet < instrumentAndRunPos(end)));

Error in ==> echodemo at 183 disp(formatError(mExc))

somebody could help me? Thanks in advance.

Problem solved: go to System-> Enviroment Variable-> System Variable and verify if there is in the Varible Path the following directories

%SystemRoot%\System32;%SystemRoot%;%SystemRoot%\System32\Wbem;%MATLAB ROOT%\runtime\win32;%MATLAB ROOT%\bin

The problem was solved after setting that.

That's good to hear. You might mark the question as answered then ...

Hi,

it looks as if the demo fails (and echodemo does not produce a "nice" error message). I would suggest to run the demo just as a script, i.e.,

edit coderdemo_hello_world

and then press the "run" button (or just press F5). Probably the demo will fail but should give a more helpful error message ...

Thank you for the help. I did the suggested,so I had the more detailed error report, but the problem persist, the error is :

What happens when you type "!cmd &" (without the quotes) from the MATLAB prompt?

Also, could you look at my comment on this page: http://www.mathworks.com/matlabcentral/answers/2926-convert-matlab-to-c-using-emlc-function

[Joao Paulo]

the DOS prompt opened and gave-me the message: "cmd is not recognized as a intern comand, batch command or a batch file"

[Joao Paulo]

I´m using Visual Studio, Do I have to install additionally gcc compiler to acess the gmake comand? I looked the topic which you have cited, and I searched for the system variable. There is a System Variable ComSpec which point to the path C:Windows\system32\cmd.exe .
