Undefined function 'nfsftmex' for input arguments of type 'char'

[Dripta Dutta]

Hello,

Once I start MTEX 5.0.2 in Matlab 2013a using command "startup_mtex", I get an error :  Undefined function 'nfsftmex' for input arguments of type 'char'.

However, I am able to open the import wizard, and import and plot pole figure data. But the moment I try to plot the ODF for the given pole figure, I get the same error mentioned above, followed by a few more (shown in the attached JPEG file).

I have just started learning MTEX and couldn't really understand where am I going wrong. I would really appreciate if anyone could help me out with this.

Hi Dripta,
what's in your folder extern/nfft_openMP or in externe/nfft inside your mtex directory?

Cheers,
Rüdiger

Hello Dr. Kilian,

I have attached the screenshots of both the folders nfft_openMP and nfft.

Hi Dripta,

I assume you are running a 64-bit os, right? It might be that 2013a is too old , maybe you could also compile the binaries yourself and see if this works.
There's a very brief description in the readme.md in that folder, you'll need fftw and the most recent development version of nfft (https://github.com/NFFT/nfft).

Cheers,
Rüdier

Hello Dr. Kilian,

No, mine is a 32-bit OS. Should I still go ahead and compile the binaries?

[ruediger Kilian]

Hi Dripta,

that explains why it's likely working for you - mtex comes only with the 64-bit version, so in that case you need to compile them for your system.

Cheers,
Rüdiger

Dear Dripta,

please find attached 32 bit compiled binaries. Please report whether they work.

Ralf.

[Dripta Dutta]

Thanks a lot Dr. Hielscher. 

Should I transfer these files into the folders nfft and nfft_openMP?

[Ralf Hielscher]

into nfft should be correct.

Ralf.

Thank You Dr. Hielscher. It's working now. I didn't get the error this time while initializing MTEX.
