As previously mentioned, you could just add a loop and do the vector
multiplication one element at a time (obviously this depends on your C
representation of yl, x, and w):

yl[k] = 0;
for (j = 0; j < n; ++j)
    yl[k] += x[i][j]*w[j][k];
yl[k] += b[k];

Or use some version of BLAS.  Or vectorize, which would help you both in
Octave and C if you use BLAS.

Or, if you're amenable to C++, check out something like Armadillo:
