I am trying to run the symmetry dectection algorithm proposed in the paper "Detecting Symmetry and Symmetric Constellations of Features".
One weird thing happend is that I can perfectly run the code without error in my laptop. But when I copy those file into my desktop computer. The mex function cannot be found. It shows the error message:
Undefined function or variable 'histc_weighted_mex'.
Error in histc_weighted (line 67)
hist = histc_weighted_mex(x,weights,edges);
Error in linear_hough (line 30)
Hough_im = reshape(histc_weighted(ind_hs,weights,[1:prod(size(Hough_im))]), size(Hough_im));
Error in symmetry (line 82)
[Hough_im, max_r, max_ang, r, sym_strength] = linear_hough(im,sym_x,sym_y,ang,phase_weight);
I have no idea why this error occur? Can anyone help me?
Both two computer are using MATLAB R2018b

Are both of them the same class of operating system? Windows mex cannot be used with Linux for example.

You are trying to use mex file generated for mac OS (as I see in the link which you provided) which doesn’t work on platforms other than mac. Since, mex file is platform specific, you can generate mex file again for your platform following the guidelines from the link provided.

I met the same problem but in my case, I just
mex private\histc_weighted_mex.c
and then the code is runed succeed.
PS. My computer is win10-64 bit with Matlab 2016B.
