I don't think there's any way of accessing the element constraint matrix efficiently except to apply its action to another dense matrix and/or vector before throwing it away. Unless someone recalls something I've forgotten? And in that case, yes, we ought to make build_constraint_matrix public. Ping us again in a week if nobody's come up with any workarounds and/or objections in the meantime. --- Roy ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.
