This project involves the development of a program to read a sparse matrix from an MM file, convert it to Compressed Sparse Row (CSR) format, and then solve for vector x using Jacobi's method.

Abstract: Our numerical experiments show that the hierarchical matrix (H-matrix) solver is more efficient than the butterfly solver for electrically small problems, although the converse is true for ...

Abstract: The sparse matrix solver has become a bottleneck in simulation program with integrated circuit emphasis (SPICE)-like circuit simulators. It is difficult to parallelize the solver because of ...
