(synopsis "Multivariate curve resolution alternating least squares")
(description
"Alternating least squares is often used to resolve components
contributing to data with a bilinear structure; the basic technique may be
extended to alternating constrained least squares. This package provides an
implementation of @dfn{multivariate curve resolution alternating least
squares} (MCR-ALS).
Commonly applied constraints include unimodality, non-negativity, and
normalization of components. Several data matrices may be decomposed
simultaneously by assuming that one of the two matrices in the bilinear
decomposition is shared between datasets.")
