  abstract     = {Multi-variable derivative \# To the people that are not used to matrix derivatives (like me) it could be useful to see how ∂ u ∂ u T S u ​ = 2 S u First, we note that if you derive with respect to some matrix, the output will be of the same dimension of that matrix. That notation}
