rksuite_90

Algorithm 771: rksuite_90: Fortran 90 software for ordinary differential equation initial-value problems We present Fortran 90 software for the initial value problem in ordinary differential equations, including the interfaces and how Fortran 90 language features afford the opportunity both to address different types and structures of variables and to provide additional functionality. A novel feature of this software is the availability of Unix scripts which enable presentation of the software for multiple problem types.
