fn dot does not do a dot product

[gautam-e]

I could be wrong here but I don't think its a dot product that is happening here in fn dot.
It's actually a step towards doing a matrix-vector multiplication, if I'm not mistaken.
I say this since its result is not a scalar but a vector of length nelts or rather B.cols/C.cols.

Here's the relevant code section:

# Simplify the code by using the builtin vectorize function
from Functional import vectorize
fn matmul_vectorized_1(C: Matrix, A: Matrix, B: Matrix):
    for m in range(C.rows):
        for k in range(A.cols):
            @parameter
            fn dot[nelts : Int](n : Int):
                C.store[nelts](m,n, C.load[nelts](m,n) + A[m,k] * B.load[nelts](k,n))
            vectorize[nelts, dot](C.cols)

Or have I got it wrong? If I got it right, I could make an issue for it but I just wanted to be sure...
