With 200,000 samples from the same mixture distribution, it doesn't return even after an hour. What is wrong? Thank you.

2012-12-19 20:02:28 -0600	asked a question	3D matrix errors: constructor, access, functions Hello, The constructor Mat image=Mat(3, dims, CV_16USC1, 0) compiles, but if I later access any element with image.at<uchar>(z,y,x) I get a segmentation fault. where int dims[]={128, 128, 1} If I scrap the last argument (that sets the elements to zero), there is no segmentation fault when subsequently accessing elements. image.dims is reported to be zero. minMaxLoc worked with a 2D matrix, but appears to check on dims and exits. Even if I set it by hand, the same happens. Please help! Thanks. S.
