Description
The MATLU Block outputs two matrices L and U, with row pivoting, from the LU factorization of a square input matrix. If A is the input matrix then:
E*A=L*U where E is the permutation matrix, U an upper triangular matrix and L a lower triangular matrix.The equivalent function of this block in Scilab is [l,u,e]=lu(A).
Dialog box
Datatype(1=real double 2=Complex)
It indicates the type of the output. It support only the two types double (1) and complex (2). If we input another entry in this label xcos will print the message "Datatype is not supported".
Properties : Type 'vec' of size 1.
