Matrix Crout Factorisation

Calculate the Crout or Cholesky LU factorisation of a square (n x n) matrix A.

Enter each matrix row as a comma separated list, with a new line for each row. Matrices must have an equal number of elements in each row.

The Crout LU factorisation is calculated so that

`L · U = A `

where :

L is a lower diagonal matrix
U is an upper diagonal matrix.

The L and U matrixes are combined into a single matrix. The U matrix has ones on the diagonal (not shown). The determinant is the product of the elements in the diagonal.
