| C++ MatObj | #include <OptiVec.h>
void matrix<T>::Cols_rotate( const int pos ); |
| Pascal/Delphi | uses MFstd;

| CUDA function Pascal/Delphi | uses MFstd;

| Description | MAi,j = MAht-pos+i, j, i=0,..,pos-1
MAi,j = MAi-pos, j, i=pos,...,ht-1
This function is rather inefficient, as it needs to internally allocate and de-allocate work-space each time it is called. If your application contains frequent calls to this function, we recommend to allocate some matrix MBuf as buffer memory and replace the calls to MF_Cols_rotate by calls to MF_Cols_rotate_buf. |
