Hello, Ineed some help with my code for solving system by using Crouts LU factorization:

x$1+$x$2-$x$3+$x$4-$x$5=2$;

$2$x$1+2$x$2+$x$3-$x$4+$x$5=4$;

$3$x$1+$x$2-3$x$32-$x$4+3$x$5=8$;

$4$x$1+$x$2-$x$3+4$x$4-5$x$5=16$;

$16$x$1-$x$2+$x$3-$x$4-$x$5=32$;

When I use the code The output is:

Some thing wrong, A not equal to LU$!$

I dont know where is my mistake!
