In this paper, a new method for solving nonlinear simultaneous equations is proposed.This method employs an initial symmetric factorization of the Jacobian matrix, and then up-dates the upper triangular factors directly at each step. Iterations are generated using forwardand backward substitutions ...

X = sort (Y) is used to sort the elements of Y in the ascending order. If input Y is a vector, the function sort (Y) will sort the elements of the vector Y. If input Y is a matrix, the function sort (Y) will treat the columns as vectors & will sort each column. X = sort...
