| Function | Signum function, compares each element of a vector with 0. |
|
| Syntax C/C++ | #include <VFmath.h>
void VF_sgn( fVector Y, fVector X, ui size ); |
| C++ VecObj | #include <OptiVec.h>
void vector<T>::sgn( const vector<T>& X ); |
| Pascal/Delphi | uses VFmath;
procedure VF_sgn( Y, X:fVector; size:UIntSize ); |
|
| CUDA function C/C++ | #include <cudaVFmath.h>
int cudaVF_sgn( fVector d_Y, fVector d_X, ui size );
void VFcu_sgn( fVector h_Y, fVector h_X, ui size );
|
| CUDA function Pascal/Delphi | uses VFmath;
function cudaVF_sgn( d_Y, d_X:fVector; size:UIntSize ): IntBool;
procedure VFcu_sgn( h_Y, h_X:fVector; size:UIntSize );
|
|
| Description | Each element of X is compared with 0 and the result of the comparison stored in Y:
Yi = +1.0, if Xi > 0
Yi = 0.0, if Xi = 0
Yi = −1.0, if Xi < 0.
This function is identical to VF_cmp0. |
