sanic's Issues

Return failed CG guess

Currently, CG estimates that fail to converge lead to an error. It might make sense to change this to a warning, and return the latest guess -- especially if the number of iterations is capped. Happens here:

Rcpp::stop("Solving failed.");

Allow more interfacing

Atm a matrix is fed in and a result is fed out. Would be interesting to cache decompositions and interface more directly with Eigen.
