This code implements a Matlab version of the benchmark in D. Aristoff and W. Bangerth, "A benchmark for the Bayesian inversion of coefficients in partial differential equations," arXiv:2102.07263.

Approximate sparsity patterns for the inverse of a matrix and preconditioning, T. Huckle, Applied Numerical Mathematics 30 (1999) 291-303. A comparative study of sparse approximate inverse ...

We implement fixed-point matrix inversion on a Virtex-4 FPGA using a synthesizable QR-decomposition MATLAB model and the AccelDSP Synthesis tool. The resulting function occupies 12% of a XC4VSX55 ...
