I have a c shared library built from a matlab function. The function executes properly till end but segmentation violation occurs on returning.
Abnormal termination:
Segmentation violation

I'm calling this in c as :
mlfRecognizeface(1, *&Recognized*, mat1, LeftEyeFilterAverage, RightEyeFilterAverage, NormImgSize, BunchGraph, BunchGraphPolar, GaborMask, Masks, DatabaseFaceGraphFront, DatabaseFaceGraphPolarFront, SimilarityThreshold, DatabaseFaceGraphRight, DatabaseFaceGraphPolarRight, DatabaseFaceGraphLeft, DatabaseFaceGraphPolarLeft, Edges);
where Recognized is the only output and all of these are of type mxArray

Hi,
seems like you are running your application out of a folder where you dont have read permissions. Please try to run your program from a folder with read permission.
