Function

rotate all rows by a specified number of positions; thereby, whole columns are moved

Syntax C/C++	#include <MFstd.h> void MF_Rows_rotate( fMatrix MA, ui ht, ui len, int pos );
C++ MatObj	#include <OptiVec.h> void matrix<T>::Rows_rotate( const int pos );
Pascal/Delphi	uses MFstd; procedure MF_Rows_rotate( MA:fMatrix; ht, len:UIntSize; pos:Integer );

CUDA function C/C++	#include <cudaMFstd.h> int cudaMF_Rows_rotate( fMatrix d_MA, ui ht, ui len, int pos ); void MFcu_Rows_rotate( fMatrix h_MA, ui ht, ui len, int pos );
CUDA function Pascal/Delphi	uses MFstd; function cudaMF_Rows_rotate( d_MA:fMatrix; ht, len:UIntSize; pos:Integer ): IntBool; procedure MFcu_Rows_rotate( h_MA:fMatrix; ht, len:UIntSize; pos:Integer );

Description

MA_i,j = MA_{i, len-pos+j},   j=0,..,pos-1
MA_i,j = MA_{i, j-pos},      j=pos,...,len-1
MA_i,j = MA_{i-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_Rows_rotate by calls to MF_Rows_rotate_buf.
