writing a for loop that solves on two arrays at the same time

say I have this: x=1:5 y=1:5

I want to compute the for loop that multiplies x and y for every element of the two arrays, for example:

[x(1)*y(1), x(1)*y(2),x(1)*y(3), x(1)*y(4), x(1)*y(5)] as well as [x(2)*y(1), x(2)*y(2),x(2)*y31), x(2)*y(4), x(2)*y(5) ] and so forth.

The easy way out would be to write 5 separate for loops for each value of x for example x=1 y=1:5 for i=1:5 product=x*y(i) end

But I want to know how I could make just one for loop

[Andrei Bobrov]

x=1:5, y=1:5

solution

n = numel(y);
out = zeros(numel(x),n);
x1 = x.';
for i1 = 1:n
    out(:,i1) = x1*y(i1);
end

without loop for..end

out = x(:)*y(:).';
