Hi everybody,

 I am trying to pass a structure array to mex function through Matlab. I have read a lot on internet but i cannot find a simple example in form of code that can explain it. Kindly can some one explain me via a simple code. For example i am trying to pass the following structure array to a mex function.

tt = 1; for i = 1:r for j = 1:c edge(tt).row = i; edge(tt).col = j; tt = tt + 1; end end end

Are you simply trying to recover the i and j values inside the mex function? Or is there a larger context or different problem you are actually trying to solve? mxGetField followed up with mxGetScalar can do the job you have requested.
