Member Function Documentation

◆ dataToImage()

std::vector< double > Mantid::Algorithms::MaxentTransformFourier::dataToImage ( const std::vector< double > & data )

overridevirtual

Transforms a 1D signal from data space to image space, performing a forward Fast Fourier Transform.

See also GSL documentation on FFT. Input is assumed real or complex according to the type of data space given to the constructor. Return value is real or complex according to the type of image space given to the constructor. If complex, input & return vectors consist of real part immediately followed by imaginary part of each individual value.

Parameters

data	: [input] Data as a vector

Returns: : The vector in the image space

Implements Mantid::Algorithms::MaxentTransform.

Reimplemented in Mantid::Algorithms::MaxentTransformMultiFourier.

◆ imageToData()

std::vector< double > Mantid::Algorithms::MaxentTransformFourier::imageToData ( const std::vector< double > & image )

overridevirtual

Transforms a 1D signal from image space to data space, performing an inverse Fast Fourier Transform.

See also GSL documentation on FFT. Input is assumed real or complex according to the type of image space given to the constructor. Return value is real or complex according to the type of data space given to the constructor. If complex, input & return vectors consist of real part immediately followed by imaginary part of each individual value.

Parameters

image : [input] Image as a vector
