| Function | Rotate the ordering of the elements of a vector |
|
| Syntax C/C++ | #include <VFstd.h>
void VF_rotate_buf( fVector Y, fVector X, ui size, int pos, fVector Buf ); |
| C++ VecObj | #include <OptiVec.h>
void vector<T>::rotate( const vector<T> X, int pos, const vector<T> Buf ); |
| Pascal/Delphi | uses VFstd;
procedure VF_rotate_buf( Y, X:fVector; size:UIntSize; pos:Integer; Buf:fVector ); |
|
| CUDA function C/C++ | #include <cudaVFstd.h>
int cudaVF_rotate_buf( fVector d_Y, fVector d_X, ui size, int pos, fVector d_Buf );
void VFcu_rotate_buf( fVector h_Y, fVector h_X, ui size, int pos, fVector h_Buf );
|
| CUDA function Pascal/Delphi | uses VFstd;
function cudaVF_rotate_buf( d_Y, d_X:fVector; size:UIntSize; pos:Integer; d_Buf:fVector ): IntBool;
procedure VFcu_rotate_buf( h_Y, h_X:fVector; size:UIntSize; pos:Integer; h_Buf:fVector );

| Description | Yi = Xsize-pos+i, i=0,..,pos−1
Yi = Xi-pos, i=pos,..,size−1
This is a more efficient variant of VF_rotate. Instead of allocating buffer memory each time the function is called, it takes the necessary buffer as the argument Buf. Buf must be a vector generated by the OptiVec memory management function (VF_vector etc.). The size of Buf must be greater or equal to the shift, pos. |
