TAUCS is a C library of solvers for sparse linear algebra.

In my geophysical work, I rely heavily upon a generalized inversion algorithm called Gauss-Newton optimization. The Gauss-Newton method minimizes objective functions that can be iteratively approximated by quadratics. This approach is particularly appropriate for least-squares inversions of m...

Analyzes accelerations caused by gravity, such as those recorded by GRACE. GAIA inverts these accelerations using a mascon technique to determine the mass distribution that matches the acceleration data. Currently, mass distributions can either be static in time, vary linearly, as well as osc...
