As other people answered, solving a symmetric matrix is another science than a 
asymmetric one. But also when the matrices get big, other storages (than array 
(Integer range <>, Integer range <>) of...) can be a better solution, like band 
or sparse matrices. In some areas a 10_000 x 10_000 matrix is a toy one, for 
testing small examples (e.g. solving a physics equation on a 100x100 grid)...
