This program finds the LU factorization of a real positive definite
matrix,
where L is unit lower-triangular.
Below enter a matrix to find its LU factorization. Enter the elements one
after
the other (row by row) and separate the elements by commas. For example,
if the
matrix (call it a) is 2 by 2 and a(1,1) = 5, a(1,2)=7, a(2,1)=9, a(2,2)=8,
then
enter the elements as follows: 5,7,9,8
When you finish click the button "Find LU Factorization".
