No coding syntax error
x(1)=1.5;
y(1)=-1;
z(1)=1;
iter(1)=0;
for n=1:4
iter(n+1)=n;
x(n+1)=(16+3*y(n)-2*z(n))/8;
y(n+1)=(-9+2*x(n+1)-z(n))/8;
z(n+1)=(1+2*x(n+1)-4*y(n+1))/10;
end
Solution = [iter',x',y',z']
Result:
Solution =
0 1.5 -1 1
1 1.375 -0.90625 0.7375
2 1.4758 -0.84824 0.73445
3 1.4983 -0.84223 0.73655
4 1.5 -0.84206 0.73683
