FunctionRelative Deviation (in absolute terms) of the elements of one vector from the corresponding elements of another vector, normalized by the larger of the two input values
Syntax C/C++#include <VFmath.h>
void VF_reldevV( fVector Z, fVector X, fVector Y, ui size );
C++ VecObj#include <OptiVec.h>
void vector<T>::reldevV( const vector<T>& X, const vector<T>& Y );
Pascal/Delphiuses VFmath;
procedure VF_reldevV( Z, X, Y:fVector; size:UIntSize );
CUDA function C/C++#include <cudaVFmath.h>
int cudaVF_reldevV( fVector d_Z, fVector d_X, fVector d_Y,ui size );
void VFcu_reldevV( fVector h_Z, fVector h_X, fVector h_Y,ui size );
CUDA function Pascal/Delphiuses VFmath;
function cudaVF_reldevV( d_Z, d_X, d_Y:fVector; size:UIntSize ): IntBool;
procedure VFcu_reldevV( h_Z, h_X, h_Y:fVector; size:UIntSize );
DescriptionZi = |Xi − Yi|  /  max(|Xi|, |Yi|),   if |Xi| > 0 or |Yi| > 0
Zi = 0,   if Xi = 0 and Yi = 0

While VF_reldevV yields the absolute value of the relative deviation, the similar function VF_reldiffV gives the relative deviation with ±sign.
