Such an eigenvalue is called the "dominant eigenvalue" of WebThe permutation matrix P has only n nonzero elements. As with dense matrices, the statement [L,U] = lu (S) returns a permuted unit lower triangular matrix and an upper triangular matrix whose product is S. By itself, lu (S) returns L and U in a single matrix without the pivot information.
