An efficient algorithm to compute the exponential of skew-Hermitian matrices for the time integration of the Schrödinger equation
Elsevier B.V. (2022-04-30)We present a practical algorithm to approximate the exponential of skew-Hermitian matrices up to round-off error based on an efficient computation of Chebyshev polynomials of matrices and the corresponding error analysis. ... -
Computing the Matrix Exponential with an Optimized Taylor Polynomial Approximation
MDPI (2019)A new way to compute the Taylor polynomial of a matrix exponential is presented which reduces the number of matrix multiplications in comparison with the de-facto standard Paterson-Stockmeyer method for polynomial ...
