Recent work uses a simplistic approximation to the matrix exponential derivative to apply gold-standard models from evolutionary biology to a collection of challenging data analyses. Whereas one may ...
matrices-expm is a collection of MATLAB functions that generate the selected matrices for testing the matrix exponential. All matrices are square and have a fixed size, ranging from 2-by-2 to 20-by-20 ...

Exponential integrators represent an innovative class of numerical methods designed to address the challenges posed by stiff differential equations. By incorporating the matrix exponential to treat ...
Abstract: The starting point is to rewrite the differential equation as an integral equation, which is then viewed as a functional equation. This makes obvious what the fixed point iteration should be ...
