Message Catalog Matlab:interpreter was not loaded

Question

I have got a very strange error in MATLAB and it doesn't seem to be directly related to my program. MATLAB doesn't even give me a line where the error occurred.

My program processes a lot of files. I can process groups of them without getting an error, but when process them all of them together I get the following error:

Caught "std::exception" Exception message is:
Message Catalog MATLAB:interpreter was not loaded from the file. Please check file location, format or contents

This usually happens at approximately the same point, but not exactly. I tested all the files around this point and they work. This is why I assume it is related to the RAM.

If I try to run the program again I get the same error right at the beginning, but after restarting MATLAB everything runs fine again.

I was wondering if it was a C++ based error, since it contains 'std::...'

Do you have any idea what this error means and how I can fix it?

Answer 1

I met this error today, but my reason is simple, I forgot to call fclose every time I wrote to a new file. After I add the fclose then the error has gone.

Answer 2

This looks like an installation problem. MATLAB is looking for a file in your installation called $MATLABROOT/resources/MATLAB/en/interpreter.xml. Check that file exists - you might need to re-install.

EDIT: turns out the problem was the OP's code was leaking file handles, meaning that MATLAB was eventually unable to open the resource file.
