Hi! I have two arrays (one generated by chi2pdf function) that I need to multiply together without using a for loop, for some values of x:
n=[1 5]; x = [0:0.4:5] chi2pdf(x,n);
is there a way to simply multiply these together in one or two lines of code? Thanks!

Element wise multiplication can be performed using the '.*' operator. So, if you have two matrices say X (n x m) and y(n x m) and you want to perform element wise multiplication, you can do so by:-
>> Z=X.*Y;
