Hi Phil,
I have been thinking for a few days on the Matrix classes.
I think the Matrix class itself should contain all those methods that do matrix calculations (add, subtract, multiply) that either a Matrix themselfs or proporties of the Matrix (isSingular for example). The mean methods (getRowMeans) etc are statistics done ON a matrix, and I think they should be in a seperate class, maybe called MatrixStats. This enables aso he option to add variances and SD's which are needed for column mean resp mean-SD standardizations, to be used for example in PCA calculations when a covariance resp. correlation matrix is used.
Is there the intention to add an EigenvalueDecomposition class to the package? In that case, which algorithm is targeted to be used? Jacobi?
