getU

org.apache.commons.math3.linear.RealMatrix getU()

Get the U matrix of a Singular Value Decomposition U has the property that V.transpose * V = I Note that U need not be square.

getPinv

org.apache.commons.math3.linear.RealMatrix getPinv()

Get the pseudoinverse as calculated using the SVD

getSingularValues

double[] getSingularValues()

Get the singular values as an array.
