How to do a gauss partial pivot?

1 次查看(过去 30 天)
Hi,
For each row, I want to find the absolute maximum and divide the other elements on the same row with the maximum. I want to do this with each row.
A = [1 2 3; 2 -1 1; 1 1 1]
n = size (A,1);
maximum = 0;
for k = 1 : n
for i = 1 : n
if abs(A(k,i)) >= maximum
maximum = A(k,i);
end
A(k,i) = A(k,i)/maximum;
end
end
A
My algorithm is not giving me the right matrix. Can you help me please?

A = [1 2 3; 2 -1 1; 1 1 1]
A = 3×3
1 2 3 2 -1 1 1 1 1
A./abs(max(A,[],2))
ans = 3×3
0.3333 0.6667 1.0000 1.0000 -0.5000 0.5000 1.0000 1.0000 1.0000
