Description Usage Arguments Value Examples
This function contributes to solve a least square linear problem using the fast combinatorial strategy from Van Benthem et al. (2004). This implementation is similar to that included in the NMF R package by Renaud Gaujoux and Cathal Seoighe, and it is tailored to the data used in the mutational signature analysis.
