FNOL2, A FORTRAN (IBM 7090) SUBROUTINE FOR THE SOLUTION OF ORDINARY DIFFERENTIAL EQUATIONS WITH AUTOMATIC ADJUSTMENT OF THE INTERVAL OF INTEGRATION

Abstract

FNOL2 is a FORTRAN subroutine used for the numerical integration of a system of up to 30 ordinary differential equations. It uses double precision arithmetic in key locations. FNOL2 has the option of automatically varying the interval of integration, h, to hold the relative or absolute truncation error within bounds fixed by the user. A FORTRAN listing of the subroutine is included in this report.
