Do you have the sourcecode that was used for the generation of the mexglx? If not, I have no clue and I assume that there is no way but code disassembly... If you have the sourcecode, create the mex-file on your own by using the mex-command and change the reference to the mexglx accordingly.

You cannot execute a Linux mex file on MS Windows. You will, as Benjamin suggests, need to rebuild the mex from source.

yeah ... i have the source code... the error that i get is
Unable to load mex file: C:\Documents and Settings\computer\Desktop\26.1\SamplePtrsFromRegionsMex.dll. The specified module could not be found.
??? Invalid MEX-file 'C:\Documents and Settings\computer\Desktop\26.1\SamplePtrsFromRegionsMex.dll': The specified module could not be found.
But , i have SamplePtrsFromRegionsMex.dll in my current working directory ..
but still i get such error msg....

How did you compile the source code? The error message appears, if you run a DLL, but some used library functions are missing.

What version of MATLAB are you using? I'm surprised that your MEX file recompiled for Windows carries the extension ".dll". I would expect it to be ".mex32".
Also, can you tell us the command line to MEX you are using, and any output MEX returns?

First i used matlab 7.0.... But now i have changed it and now i use matlab 7.9.
i got .mexw32 files created. But when i start running the codes in matlab7.9, i get the following error
Invalid MEX-file 'D:\pathname\myMex.mexw32': The specified module could not be found.
However, this .mexw32 file is located in my working directory. But still i get that error.

I've asked you already: How did you compile the C-file? The error message appears e.g., if you compile the C-file on one computer with MSVC, but run it on another computer without installing the required distributables.

i got the code from the link,
http://www.cs.utexas.edu/~grauman/research/software.html
Its BPLR code. I first compiled two .m files 'bplr_startup.m' and 'bplr_compile_mex.m', as it was mentioned in README.
I got the above said error when i compiled 'bplr_compile_mex.m'.
When i compiled the program , i got the following error..
Extract BPLR... multiple segmentations... 146 segments obtained sampling ptrs... ??? Undefined function or method 'SamplePtrsFromRegionsMex' for input arguments of type 'cell'.
Error in ==> uniformSamplePtrsFromRegions_ at 25 [dt_max sample_ptrs] = SamplePtrsFromRegionsMex(dt, bbox, grid_spacing);
Error in ==> createUniformSamplePtrsFromDT_ at 8 [ptrs scales ptrs_region] = uniformSamplePtrsFromRegions_(regions, sample_grid_spacing, supp_radius_thresh);
Error in ==> detectBPLR at 25 [ptrs edges scales] = createUniformSamplePtrsFromDT_(regions, im, ucm, contour_im, order_k, sample_grid_spacing);
Error in ==> demo at 111 BPLR = detectBPLR(im, ucm, gPb_thin, order_k, euc_f, im_dim, min_nseg, max_nseg, grid_space, min_elem_scale);

So sir, can u please see that link and run it in ur computer.

We compiled the .cc files using a MSVC 6.0 compiler and got the .mexw32 one.
