Attempt:
This is my code so far:
Code:
clear all
clc
clf
function x=GaussSeidel(A,b,y,N)
n = length(y);
for k = 1:N
for i=1:n
s=b(i);
for j =1:i-1
s=s-A(i,j)*y(j);
end
for j = i+1:n
s=s-A(i,j)*y(j);
end
x(i)=s/A(i,i);
x(i)=x(k);
end
y = x'
end
However I am getting the following error: Code:
Error: File: Untitled.m Line: 4 Column: 1
Function definitions are not permitted in this context.
Why am I getting this error? What do I need to do?
And my inputs are:
Code:
A=[-5 0 2 0 -1 ;
0 9 0 3 0 ;
2 0 5 0 2 ;
0 -2 0 4 0 ;
-1 0 7 0 7]
b = [8;4;-8;-4;0]
x0=[8;4;-8;-4;0]
For N, how do I know many iterates N are necessary for this problem?
Any help with the code is greatly appreciated.
