Faktorisasi LU dengan metode crout

Algoritma faktorisasi LU dengan metode crout

Source program MATLABnya adalah seperti berikut

function [l, u]=crout(a)
    n=size(a,1)

    for j=1:n,
        m(j,1)=a(j,1)
        u(j,j)=1
    end
    for k=2:n,
        u(1,k)=a(1,k)/m(1,1)
    end
    for j=2:n,
        for k=2:j,
            m(j,k)=a(j,k)-m(j,1:k-1)*u(1:k-1,k)
        end
        for k=j+1:n
            u(j,k)=(a(j,k)-m(j,1:j-1)*u(1:j-1,k))/m(j,j);
        end
    end

    l=m
    
endfunction
