	Linear to decibel scale transformation. More...
1D Fast Fourier Transform.
This Fourier transform is a Fast Fourier transform taken from the Numerical Recipee in C. Parameters vec 1D-input data of complex float items isign +1 for direct transform and -1 for inverse transform
AIMSALGO_API AimsData< float >	AimsXCor1d (const AimsData< float > &data1, const AimsData< float > &data2)
1D Cross-correlation.
This cross-correlation is based upon Fast Fourier transform taken from the Numerical Recipee in C. Parameters vec 1D-input data of complex float items vec 1D-input data of complex float items
