Detailed Description
Matrix elements are stored row by row.
Element (i, j) (i - 0-based row index, j - 0-based column index) of a matrix can be retrieved or modified using CV_MAT_ELEM macro:
uchar pixval = CV_MAT_ELEM(grayimg, uchar, i, j) CV_MAT_ELEM(cameraMatrix, float, 0, 2) = image.width*0.5f;
To access multiple-channel matrices, you can use CV_MAT_ELEM(matrix, type, i, j\*nchannels + channel_idx).
