Also, , routines communicate with each other by means of labelled , COMMON blocks. They are described and details of their , usage by the routines are given. file ode/rksuite/templates for samples of how to use the suite to solve typical problems. , Each template comes in two variants. An output file for , each template showing the results of the use of the , template in both its variants is provided. Other , choices of methods are possible in some templates; , output using them is included in the output file. , That is, there are nine files in total (six with , extension .f and three with extension .out). file ode/rksuite/readme file ode/rksuite/rksuitec++.zip lang C++ by Don Linton lintond at infowaresystems.com .
