Functiontwo-dimensional Welch window for use in spatial frequency analysis
Syntax C/C++#include <MFstd.h>
void MF_Welch( fMatrix MA, ui ht, ui len );
C++ MatObj#include <OptiVec.h>
void matrix<T>::Welch( );
Pascal/Delphiuses MFstd;
procedure MF_Welch( MA:fMatrix; ht, len:UIntSize );
CUDA function C/C++#include <cudaMFstd.h>
int cudaMF_Welch( fMatrix d_MA, ui ht, ui len );
void MFcu_Welch( fMatrix h_MA, ui ht, ui len );
CUDA function Pascal/Delphiuses MFstd;
function cudaMF_Welch( d_MA:fMatrix; ht, len:UIntSize ): IntBool;
procedure MFcu_Welch( h_MA:fMatrix; ht, len:UIntSize );
DescriptionMAi,j = (1 - ( (i - 0.5*(ht - 1)) / (0.5*(ht + 1)) )2) * (1 - ( (j - 0.5*(len - 1)) / (0.5*(len + 1)) )2)
This function provides a window for spatial power-spectrum estimation with Welch's method of overlapping segments, here implemented as MF_spectrum.
