Requested 250000x250000 (931.3GB) array exceeds maximum array size preference

I have two vector x1 and x2 each of length 250,000X1 samples that I want to multiply them elementwise as below, but I get the error that array exceeds maximum array size preference. How can I solve this issue?
x1.*x2

One of them is a 1x250000 row vector. You can transpose that one, or you can convert it (or both) to column vector(s):
x1(:).*x2(:) % 250000x1
