A numerical integrator written in Elixir for the solution of sets of non-stiff ordinary differential equations (ODEs).

Runge-Kutta adaptive-step solvers for nonlinear PDEs. Solvers include both exponential time differencing and integrating factor methods.

PNPG algorithm implementation and examples

A MATLAB routine to compute numerically the solution to the 1D stationary Schrödinger equation in the highly oscillatory regime.

Spectral Integration and Differentiation Algorithms. Includes FFTs, Chebyshev Transforms, and Hankel transforms. Exponential time differencing and integrating factor Runge-Kutta methods.
