phipm

phipm is the Matlab package described in ”A Krylov subspace algorithm for evaluating the φ-functions appearing in exponential integrators” by Jitse Niesen and Will Wright. To install, copy the files phipm.m and expmnorm.m to a directory where Matlab can find them. Alternatively, download phipm.tar.gz (8.4 MB) which contains these files and scripts to reproduce the plots in the paper.
