hi , can anyone tell me what's wrong with this!! please!

thank you in advance!

> crout := proc (A::array, n::integer)

local L, U, j;

L := matrix(n, n, 0);

U := matrix(n, n, 0);

L[1, 1] := A[1, 1];

L[2, 1] := A[2, 1];

U[1, 2] := A[1, 2]/L[1.1];

for j from 2 to n-1 do

did someone know the program of crout matrix decomposition?!

thank you in advance :)

hi , can anyone tell me what's wrong witht his! please!!

Fixed point method:

local n, nmax, e;

e := 1/100000000; nmax := 500;

while (evalb(n < nmax) and e < abs(g(p)-p) do

n := 1;

p := g(p); print(n, "             ", evalf(p, 10...
