Matrices with interval coefficients in Julia

Multiprecision matrix exponential

A Python class to apply the imaginary exponential of a matrix (real tridiagonal or complex) using Fortran code; these functions apply well to solve the small matrix exponential which occurs for Lanczos or Arnoldi propagator of Schrödinger-type problems

Quantum simulation using matrix exponentials and Lie-theoretic Trotterization. Lecture 6 from the Lie Groups with Applications series by Quantum Formalism.

Julia package for adaptive matrix exponential based on tolerance

Computing the matrix exponential with an optimized Taylor polynomial approximation

Infinite Matrices and Its Application

Calculators for basic needs for solving problems related to matrices and graphs

Practical shift choice for Shift-And-Invert method

Highly optimised C implementation of matrix exponential using Al-Mohy & Higham's algorithm, featuring advanced performance techniques like vectorization and LU decomposition.

Shared C++/Eigen native library for the Crystallography suite: eigenvalue decomposition and matrix exponentials for dynamical diffraction, HRTEM image formation, pseudo-Voigt fitting, and histograms.
