Hmmm, description is a little confusing. Is length(x) always = length(y)? Are they nx1 or 1xn? Anyhow, I submitted several possible solutions (e.g. z = x'*y, z = sum(x.*y)) all of which failed the test suite ... but they work fine on my machine!

Note that the output variable in the pattern is y, not z.

ha, yeah. thanks for commenting about that. I didn't see it either.
