New to Matlab, Combining Double

I have a 15x1 double and a 1x15 double, how can i combine them to create 15x15 double?

Hello Meg,

there are lots of ways to do this, depending on what you would like the result to be. For example, if a is 15x1 and b is 1x15, then a*b, the outer product, is 15x15. Starting about five years ago Matlab introduced explicit expansion, so in newer versions of Matlab, the 'outer sum' a+b is also 15x15. Lots of possibilites.
