	Hadamard product; that seems to be it. – Šime Vidas Dec 2 '12 at 18:13
	Could you explain what `e` is? – Šime Vidas Dec 2 '12 at 18:16
	$e_i$ is (AFAIK) universal notation for a vector with $1$ at the $i^{th}$ location and $0$ everywhere else. So, $e_1 \in \mathbb{R}^3$ is $[1 \quad 0\quad 0]^T$. – Inquest Dec 2 '12 at 18:17
