sortMatrix

whether the sort should be done column-wisely or row-wisely.

the matrix to be sorted. It must be a multi-dimensional tensor of 2 dimensions. Its data type must either be non-pixel datatype, or RED-channel-only pixel types. Multi-channel pixel types such as RG_FLOAT, or R8G8B8A8_U are not allowed.

the optional result to store the sorted matrix. The tensor must have the the same init info as the source, i.e., the same dimensions and the same datatype.

the optional result to store the original indices of matrix elements in source's row/column, according to the sortType. It must be a multi-dimensional tensor with the same dimensions as the source, but its datatype must be integral and must not be a multi-channel pixel type, e.g., DataType.INT16 is accepted, but DataType.Image.R16G16_S is not.

If the usage is not allowed by the SpatialML run-time Framework, or if the framework encounters internal error and cannot perform the requested behavior.
