LU Decomposition / LR-Zerlegung v0.5

Enter an NxN matrix in the field 'Matrix A' - row by row, separating the elements with spaces /or tabs/. The resulted matrices P, L and U, such that PxA = LxU (P is a permutation matrix), will appear respectively in fields 'Matrix P', 'Matrix L' and 'Matrix U'.

You can enter fractions (floating numbers) using '/' (slash) -> 1/2, 3/4 or '.' (dot) -> 0.5, 0.75. The result appears always with slashes.
