WorksheetAnalysisGetXOfSpectra Method

Returns the corresponding x-values of the spectra (In fact only the first spectra is used to determine which x-column is used).

Namespace: Altaxo.Calc.Regression.Multivariate
Assembly: AltaxoBase (in AltaxoBase.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static double[] GetXOfSpectra(
	DataTable srctable,
	bool spectrumIsRow,
	IAscendingIntegerCollection spectralIndices,
	IAscendingIntegerCollection measurementIndices
)

Parameters

srctable  DataTable
The source table where the data for the spectra are located.
spectrumIsRow  Boolean
True if the spectra in the table are organized horizontally, false if spectra are vertically oriented.
spectralIndices  IAscendingIntegerCollection
The selected indices wich indicate all (wavelength, frequencies, etc.) that belong to one spectrum. If spectrumIsRow==true, this are the selected column indices, otherwise the selected row indices.
measurementIndices  IAscendingIntegerCollection
The indices of all measurements (spectra) selected.

Return Value

Double
The x-values corresponding to the first spectrum.
