- Laso
- Fortran IV subroutines for computing a few eigenvalues of a large (sparse) symmetric matrix.

- SLEIGN2
- Code to compute eigenvalues and eigenfunctions of regular and singular self-adjoint Sturm-Liouville problems.
- 3646
- Blended Implicit Methods (BiM)
- Fortran 77 code implementing a variable order-variable stepsize method for (stiff) initial value problems for ODEs. The order of the method varies from 4 to 14, according to a suitable order variation strategy.

- DVERK
- Fortran 77 subroutine written by Hull, Enright and Jackson for the numerical solution of systems of initial value problems for ordinary differential equations.
- 3649
- Initial Value Problems
- The code GAM numerically solves solves first order ordinary differential equations, either stiff or nonstiff in the form y'=f(x,y), with a given initial condition. The code GAMD is a generalization of GAM for the solution of Differential Algebraic Equations of index less than or equal to 3 in the form M y' = f(x,y), with a given initial condition. By Francesca Mazzia.
