InnerProductComputer was assuming that the input matrix had at least one structurally non-zero block. As a result sometimes when InnerProductComputer.SubMatrix test generated matrices where the submatrix was structurally zero it would cause a segmentation fault. This changes fixes this issue and reduces the threshold for the minimum block density so that there is a much higher chance of such matrices occuring as part of testing.

Ceres Solver
Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.
- Non-linear Least Squares problems with bounds constraints.
- General unconstrained optimization problems.
