Find max cell and its location

I have two vector x and y. I did maultiplication for coreesponding cell as belwo

x=[1 3 5 7 2 0 4];

y=[2 4 6 1 6 8 1];

for i=1:7

z(i)=x(i)*y(i);

end

w=max(z)

%%%%%%%%%%%%

the answer is

z = [ 2 12 30 7 12 0 4]

w = 30

I need to know the location of value w in z vector and i expect the answer to be

index_w= 3

Hi Nasser:

You can perform in an easy way.

V = 2*(1:10)                % An arbitrary vector
     
[M,I] = max(V)              % Where M = maximum and I = the index of V

The code produces the following

V =

2 4 6 8 10 12 14 16 18 20

M =

20

I =

10
