First thing...you are in a wrong place..

To answer your question, when you are mexing you need to provide all
the SUPPORTED  .c files as arguments where the function definitions
and function declarations are present.

Hi,
  Does anybody have any experience in using the mex file provided by
xilinx core-generator for xfft_v5 to model the characteristics of the
bit-accurate FFT FPGA core in matlab?
   I put the mex file in the same directory as where i am running
matlab. and follow the instructions closely on how to call the mex
function

this is the error i get.

?? invalid mex file C:\xfft_v5_0_bitacc_cmodel_mex.mexw32. the
specified module could not be found

Error in use_mex 11
[output, blkexpm, overflow] = xfft_v5_0_bitacc_mex(generics, 10,
input, scaling_sch,1 );

I have merely copied the matlab contents from page 19 of the pdf user
guide. It can be downloaded from here.

I am using the same matlab 7.3 version as described and have put the
mex file in the directory which i am running the command.
