This is a fast implementation of exponential matrix for large full/sparse matrices, commonly found in (quantum) physics simulations. It is significantly faster than Julia's exp implementation for ...

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 ...

Abstract: This letter proposes an efficient method for calculating the eigenvalues of large-scale exponential correlation matrices by leveraging tridiagonal matrix theory. The approach explicitly ...

Abstract: Matrix exponential has many applications in science and engineering, including in the solution of differential equations and transient analysis of continuous-time Markov chains. One of the ...

Matrix functions, such as the exponential, square root and cosine, play an indispensable role in various fields including quantum mechanics, control theory and numerical solution of differential ...

This paper shows the usefulness of the exponential upwinding technique in convection diffusion computations. In particular, it is demonstrated that, even when convection is dominant, if exponential ...

In a preceding paper, the theoretical and experimental, deterministic and random, scalar and vector, kinematic structures, the theoretical and experimental, deterministic-deterministic, ...
