Hi all. I have data matrixes x(15x16) and y(15x16). And I want to create new matrix z(15x16) by taking some columns of x and y. For example, 3-4-5-10-12-14-16th columns will be taken from x and others from y. Is it possible with loop?

You don't need a loop
out=y
idx=[3 4 5 10 12 14 16]
out(:,idx)=x

Yes, there is a mistake in the last line
y=zeros(15,16);
x=randn(15,16);
out=y
idx=[3 4 5 10 12 14 16]
out(:,idx)=x(:,idx)
