tried using the example for .* Why am I getting an error?
>> a = [1 2 3]
a =
1 2 3
>> b = (1:6)'
b =
1
2
3
4
5
6
>> a.*b
Error using .*

a .* b returns a vector c where c(1) = a(1) * b(1), c(2) = a(2) * b(2), etc. but in your example you run out of values of a. For this to work, a and b have to have the same number of elements!

This message from the Related Content section on the right side of this page is relevant. You're using a release prior to release R2016b, right? See also this post on Loren's blog.
