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 ...

In this note a theoretical analysis of some Krylov subspace approximations to the matrix exponential operation exp(A)v is presented, and a priori and a posteriori ...

We introduce a new class of exponential integrators for the numerical integration of large-scale systems of stiff differential equations. These so-called Rosenbrock-type methods linearize the flow in ...
