perl-Math-RungeKutta

Algorithms for numerical integration

This module offers algorithms for the numerical integration of simultaneous differential equations of the form dY/dt = F(t,Y) where Y is an array of variables whose initial values Y(0) are known, and F is a function known from the dynamics of the problem.

This module offers algorithms for the numerical integration of
simultaneous differential equations of the form  dY/dt = F(t,Y)
where Y is an array of variables whose initial values Y(0) are
known, and F is a function known from the dynamics of the problem.

Three main algorithms are offered.  rk2 is Heun's 2nd-order Runge-Kutta
algorithm, which is relat
