Thread: Crout algorithm to finding LU decomposition

1. Crout algorithm to finding LU decomposition

Can someone give me an example of how this works...i already know how to do dolittle method but I cant find a numerical example of crout and the general theory is Chinese to me...I'm an engineer.

take a simple 3x3 matrix

2. If you can 'do' Doolittle then you can 'do' Crout.
With Doolittle you put 1's down the lead diagonal of the L matrix and then calculate the remaining non-zero elements in both the L and U matrices, with Crout you start with 1's down the lead diagonal of the U matrix and then again calculate the remaining no-zero elements.
