LSODE; ordinary differential equations system solver. [IBM370,303x; CDC7600,6600,CYBER175; FORTRAN IV]

Technical Report ·
OSTI ID:6360384

LSODE is a package of subroutines for the numerical solution of the initial value problem for systems of first order ordinary differential equations. The package is suitable for either stiff or nonstiff systems. For stiff systems the Jacobian matrix may be either full or banded. LSODE can also be used when the Jacobian can be approximated by a band matrix.IBM370,303x;CDC7600,6600,CYBER175; FORTRAN IV; OS/370 (IBM370,303x), NOS/BE 1.3 (CDC6600), ORDER, CHAT or SCOPE 2.1 (CDC7600), NOS 1.3 (CDC CYBER175); Storage requirements are highly problem-dependent. The sample problem required 24,000 (octal) words of memory on a CDC CYBER175 or CDC6600 and 88K bytes of memory on an IBM3033..
