Sstcal

Purpose

Create and apply Spectral Subspace Transformation calibration transfer.

Synopsis

[stdmat, stdvect] = sstcal(spec1,spec2,ncomp,options)

Description

Develops a mapping from one spectra space to another based on common factors using SVD. For more information see this article.

Inputs

• spec1 = M by N1 spectra from the standard instrument, and
• spec2 = M by N2 spectra from the instrument to be standarized.

• ncomp = Number of PCs to use.

Outputs

• stdmat = the transform matrix, and
• stdvect = the additive background correction.

Note: if only one output argument is given, no background correction is used.

Options

options = a structure array with the following fields:

• waitbar: ['off' | {'on'}], governs display of waitbar.
