We have detected some compatibility issues with MATLAB releases older than 2015a. Therefore, there is an MCR-ALS toolbox version for recent MATLAB releases and another MCR-ALS toolbox version for the older MATLAB releases (only visual differences between them).
These new versions have some new option in the MCRBANDS program (selection of optimization algorithm, number of iterations, …)
You can download these new versions from the “Download” section.
