Computes an upper triangular table in LU decomposition.
ULU(a)
a |
- |
A square matrix. |
A matrix.
x = {{1, 2, 3},
{4, 5, 6},
{7, 8, 10}}
ulu(x) = {{7.000, 8.000, 10.000},
{0.000, 0.8571, 1.571},
{0.000, 0.000, -0.5}}
For the LU decomposition of a square matrix A:
A = llu(A) *^ ulu(A)
also:
A = lu(A, 0, 1) *^ lu(A, 1, 1)
See LU for a further discussion of LU decomposition.
