Method Detail

decompose

public boolean decompose(org.ejml.data.ZMatrixRMaj orig)

This implementation of LU Decomposition uses the algorithm specified below: "Numerical Recipes The Art of Scientific Computing", Third Edition, Pages 48-55

Parameters:

orig - The matrix that is to be decomposed. Not modified.

Returns:

true If the matrix can be decomposed and false if it can not. It can return true and still be singular.
