The MATLAB ODE Suite [PDF]

open access: yesSIAM Journal on Scientific Computing, 1997
The paper presents mathematical and software developments that are the basis for a suite of programs for the solution of initial value problems \(y' = F(t,y)\), with initial conditions \(y(t_{0}) = y_{0}\). The solvers for stiff problems allow the more general form \(M(t)y' = f(t,y)\) with a nonsingular and sparse matrix \(M(t)\).
