Detailed Description

MaxentTransformMultiFourier : Defines a transformation from data space to image space (and vice-versa) where spaces are related by a 1D Fourier Transform, in which which the data has multiple spectra concatenatenated.

In transforming from data to image, the spectra are added together before tranforming to a single image. In transforming the image to data, copies to the transformed data (one for each spectrum) are concatenated and then have the supplied adjustments applied.

The concatenated format of the data is chosen to enable existing code to calculate its chi squared.

◆ dataToImage()

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

overridevirtual

Transforms a 1D signal from data space to image space, performing a forward Fast MexentTransformFourier on the sum of the spectra.

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 of concatenated spectra

Returns: : The vector in the image space

Reimplemented from Mantid::Algorithms::MaxentTransformFourier.

◆ imageToData()

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

overridevirtual

Transforms a 1D signal from image space to data space, performing an a backward MaxentTransformFourier on it then creating a concatenated copy of the resulting data for each spectrum and applying the adjustments to them.

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

Returns: : The vector in the data space of concatenated spectra

Reimplemented from Mantid::Algorithms::MaxentTransformFourier.

◆ setAdjustments()

void Mantid::Algorithms::MaxentTransformMultiFourier::setAdjustments	(	const std::vector< double > &	linAdj,
		const std::vector< double > &	constAdj
	)

Sets the adjustments to be applied to the data when converted from image.

Parameters

linAdj	: [input] Linear adjustments as complex numbers for all spectra concatenated
constAdj	[input] Constant adjustments as complex numbers for all spectra concatenated
