WebMCR-ALS (standing for Multivariate Curve Resolution - Alternating Least Squares) is a popular method for resolving a set (or several sets) of spectra X of an evolving mixture … Websearch strategy and fminsearch algorithm. Moreover, the magnitude of the L 0, L 1 - and L 2-norms of all mass spectra in AFSs were calculated and visualized as contour plots. The results revealed that the gradient of optimization surface for minimization of L 1-norm is much more than those seen for minimization of L 2-norm. Therefore ...
