I have a very basic problem. I want to replace some entries of zero matrix with the elements of another non zero matrix. I tried with for loop by using conditional statements. But it didn't work.
x = [1 2 3 4], Y= [0 0 0 0 0 0 0 0 0 0]
desired output
z = [1 2 3 4 0 0 0 0 0 0]
So anyone please help. Thanks in advanced

z=Y;
z(1:length(x))=x;
