%1 is not a valid Win32 application. (libfftw31.dll)

Hi all

I have a problem when running code below: I=fft2(im);

error code: libmwfftw: load error: libfftw3i.dll Caught "std::exception" Exception message is: libfftw3i.dll

I'm sure this code have no problem, because I can run it before.

Thank you.

It seems like this kind of error can occur if you have the wrong version of the fftw libraries on your system PATH - did you install/remove these libraries recently? I'm not really sure how you can fix this issue - perhaps you can try re-installing MATLAB if that's not much trouble?

I think it's my computer problem, I just remember my PC crashed before and auto recovery. I will try to reinstall MATLAB and try again, thanks for your reply.
