Inverse Of A 3x3 Matrix Contact Php Contact Php

finds null space and range of a sparse matrix using lu decomposition.This routine is devoted to find null space of possibly large matrix fast.Results may be inaccurate if zero and nonzero singular values are not well separated.

This function calculates the percentage of time that a given 3D Matrix exceeds some threshold value.It counts each point along the 1st Dimension that exceeds the threshold and expresses this as a percentage of the length of the 1st Dimension. This is repeated across the 2nd and 3rd Dimensions....
