NxN matrix in the field
'Matrix A' -
row by row, separating the elements with spaces /or tabs/.
The resulted matrices
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.
