I'm trying to compile a .mlapp file using the MATLAB Compiler. The app does not produce any errors when I run the uncompiled version, and none of my scripts show any 'impossible to run' red error lines.

However, when I try to compile the .mlapp file (which in turn checks the content of all the subfunctions, of which there are hundreds), I am presented with a rather useless error message that simply states:

File analysis cancelled because the following error occurred:
Cell contents reference from a non-cell array object.

There is no line number or filename specified. Given that there are hundreds of files that this error could reside in, I have no idea where to begin.

Is there some way of obtaining more detail about where the error has been detected? Specifically, a filename and line number...

Turn on stop on errors:

dbstop if error

Now the debugger should stop when the error occurs. If it does not, try dbstop if caught error.

Thanks for this. Using...

dbstop if error

...returns an error in the 'InspectorFactory' function, which appears to be a MATLAB core function (i.e. it has nothing to do with my code). This isn't helpful either, as there is no traceback suggesting there is anything wrong with my code...

@Matthew: Please show us, where the error occurs. This is the only information, you have about the problem currently, but the readers in the forum do not know any detail. Instead of claiming, that this information is not useful, examine, what happens. Perhaps the problem is caused by a user-defined function, which shadows a built-in function of Matlab and replies a different output. We cannot guess the reasons, but you can start the investigations.
