riccati

A package implementing the adaptive Riccati defect correction (ARDC) method

About

riccati is a Python package for solving ODEs of the form

$$ u''(t) + 2\gamma(t)u'(t) + \omega^2(t)u(t) = 0,$$

on some solution interval $t \in [t0, t1]$, and with initial conditions $u(t0) = u0$, $u'(t0) = u'0$.

riccati uses the adaptive Riccati defect correction method -- it switches between using nonoscillatory (spectral Chebyshev) and a specialised oscillatory solver (Riccati defect correction) to propagate the numerical solution based on its behaviour. For more details on the algorithm, please see Attribution.
