|Function||Compares each element of a vector with 0 (signum function).|
|Syntax C/C++||#include <VFmath.h>
void VF_cmp0( fVector Y, fVector X, ui size );
|C++ VecObj||#include <OptiVec.h>
void vector<T>::cmp0( const vector<T>& X );
procedure VF_cmp0( Y,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 may also be called under its synonym VF_sgn.
