computeedge thinning algorithm source code in MATLAB

I am trying to apply a thinning algorithm same as the thinning applied in the sobel filter. I looked at the edge.m for the algorithm but looks like it calls a mex file computeedge for the thinning. I could not find the source code of the mex file. What does this mex file exactly do? What is the thinning algorithm it performs??? Where can I find the source code for this mex file?? The thinning is called in edge.m as shown below:
function e = computeEdgesWithThinning(b,bx,by,kx,ky,offset,cutoff)
% This subfunction computes edges using edge thinning.
bx = abs(bx); % necessary for doing local maxima suppression
by = abs(by);
e = computeedge(b,bx,by,kx,ky,int8(offset),100*eps,cutoff);

If it's a mex file, they did that for speed and/or they don't want you to see the actual source code. Regardless, they will however usually give you the citation of the paper that has the algorithm they implemented (if there is such an article that they followed), but you need to ask them specifically for it. Not sure why you need to know it anyway. Do you have a problem with how it's thinned?

Did you ever find a solution? I am dealing with the exact same issue now. Thanks
