These files constitute a stiff ode solver (with sample use) in fortran. You must edit d1mach.f for your machine. It is currently figured for a SUN-3. README this file address address of source for lsode.c answer results from example test problem cmds some picsure plotting commands daxpy.c ddot.c dgefa.c dgesl.c dscal.c example.c sample usage idamax.c lsoda.c the main ode solver lsoda.doc some docs from the original fortran distribution makefile a makefile for the example, NOTE level 4 optimization does not work with lsoda.c make libq.a wil make a library containing these routines.
