A graphical user-friendly interface for MCR-ALS: a new tool for multivariate curve resolution in MATLAB

A new graphical user-friendly interface for Multivariate Curve Resolution using Alternating Least Squares has been developed as a freely available MATLAB toolbox. Through the use of this new easy-to-use graphical interface, the selection of the type of data analysis (either individual experiments giving a single data matrix or the more powerful simultaneous analysis of several experiments using one or more techniques) and the selection of the appropriate constraints can be performed in an intuitive and easy way, with the help of the options in the graphical interface. Different examples of use of this interface are given. (c) 2004 Published by Elsevier B.V.
