compiled version of m file "has invalid content" ?

I have an m file that runs when called from another function at the Matlab command line. When I compile the code, I get no errors. But, when I run the generated executable from a DOS command window, I get an error saying the m file 'has invalid content. Details: 'file is closed. failbit is set.'

Any ideas of what the problem is and how it can be fixed?

Is polyspace involved?

Hi Walter,

The following questions help to better understand the reasons for this issue:

• Can you execute the code from MATLAB without any errors?
• What is the m file? Is it a script or a function? If it is a function, what are the input arguments to it? What is the output?
• What is the purpose of the m file?
• Are you running the executable from the same machine or is it a different machine?

Thanks,

Udaya.

I don't know the answers to those, the original poster Amanda would know.
