High-performance computation of large sparse matrix exponential
Authors: Feng Wu, Kailing Zhang, Li Zhu, Jiayao Hu
In this paper, we discussed the sparsity of the matrix exponential, and found that for the matrix exponential,
there exists an approximate sparse matrix exponential under the given error tolerance.
We developed the relationship between the exact and approximate matrix exponential. And, we propose a new algorithm
for the calculation of large sparse matrix exponential.
Type: MATLAB code
Contents: This is the MATLAB function of the proposed algorithm for the computation of matrix
(2021.12.10)'mfp_exp2.rar' is the second version of the MATLAB function of the proposed algorithm for the
matrix exponential. In this version, the filtering is programmed in C language. This version is only suitable for
the real sparse matrix.
Contents: These are the 30 sparse matrices used in the subsection 5.3 of our paper.
