In C, the header file for this function includes a convenient macro ``cvReshapeND`` that does away with the ``sizeof_header`` parameter. So, the lines containing the call to ``cvReshapeMatND`` in the examples may be replaced as follow:
::
gray_img = (IplImage*)cvReshapeND(color_img, &gray_img_hdr, 1, 0, 0);
...
row = (CvMat*)cvReshapeND(mat, &row_header, 0, 1, 0);
