Hello Everyone,
let say for example I have two variables y with 25 data and x1 with 25 data. so for 1st iteration I will calculate x1*y. Than for second iteration I have to include a new variable x2 and than I have to calculate x1*y and also x2*y. and similarly with every iteration I have to calculate till x6*y.

With loop:
N = 7;
xy = zeros(numel(x),N);
xy(:,1) = x .* y;
for k = 2:N
xy(:,k) = xy(:,k-1) .* y;
end
Without loop:
XY = cumprod([x .* y, repmat(y,1,N-1)],2);

column = x.*y;
iter = 0;
while iter < 6
[calculate new x-vector];
column = [column ; x.*y];
iter = iter + 1;
end
