Techniques to factorise different linear systems and matrices.
lslu.m can be used to implement the LU Factorisation method for solving the Least Squares problem for m>n. Inputs and outputs are described in the code.
lq.m is used to compute the QL factorisation of a general dense matrix A.
ipowergen.m will solve a linear system with Av=lambda*Mv, a tolerance threshold and max number of iterations
