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.
