Functions
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
carto::VolumeRef< float >	AimsXCor1d (const carto::rc_ptr< carto::Volume< float > > &data1, const carto::rc_ptr< carto::Volume< 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
carto::VolumeRef< cfloat >	AimsFFT1D (const carto::rc_ptr< carto::Volume< cfloat > > &vec, int isign=1)
carto::VolumeRef< float >	AimsLinearToDecibel (const carto::rc_ptr< carto::Volume< float > > &sqv)
	Linear to decibel scale transformation.
