sortIdx function

Mat sortIdx(
  1. InputArray src,
  2. int flags, {
  3. OutputArray? dst,
})

SortIdx sorts each row or each column of a matrix. Instead of reordering the elements themselves, it stores the indices of sorted elements in the output array

Implementation

Mat sortIdx(InputArray src, int flags, {OutputArray? dst}) {
  dst ??= Mat.empty();
  cvRun(() => ccore.Mat_SortIdx(src.ref, dst!.ref, flags));
  return dst;
}
