| Function | "running" sum, also called "cumulative sum" or "inclusive sum-scan" |
|
| Syntax C/C++ | #include <VFstd.h>
void VF_runsum( fVector Y, fVector X, ui size ); |
| C++ VecObj | #include <OptiVec.h>
void vector<T>::runsum( const vector<T>& X ); |
| Pascal/Delphi | uses VFstd;
procedure VF_runsum( Y, X:fVector; size:UIntSize ); |
|
| CUDA function C/C++ | #include <cudaVFstd.h>
int cudaVF_runsum( fVector d_Y, fVector d_X, ui size );
void VFcu_runsum( fVector h_Y, fVector h_X, ui size );
|
| CUDA function Pascal/Delphi | uses VFstd;
function cudaVF_runsum( d_Y, d_X:fVector; size:UIntSize );
procedure VFcu_runsum( h_Y, h_X:fVector; size:UIntSize );
|
|
| Description | Each element of Y is the sum of the corresponding and all preceding elements of X. |
|
| Error handling | none (but be careful: this function may easily overflow!) |
