I have received a reply from Erin Catto and have permission to post it here for others' benefit: " 1) Right, they are both dot products. JV doesn't need the dot because you can view J as a row vector and V as a column vector, whereas J and B are both row vectors. 2) That is a typo, eta is s-by-...

Howdy, Trying to follow along "iterative dynamics with temporal coherence, catto 2005" and I've some parts that need clarification: 1) Algorithm 1 on page 7 has: J_sp(i, 1)V(b_1) and Algorithm 4 on page 17 has: J_sp(i, 1) * B(1, i) Presumably both are dot products between 6-vectors or does...
