%0Computer Program %TOrdinary Differential Equation System Solver %XLSODE 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 treated in either full or banded form. LSODE can also be used when the Jacobian can be approximated by a band matrix. %AHindmarsh, Alan %Rhttps://doi.org/10.11578/dc.20180614.12 %Uhttps://www.osti.gov/doecode/biblio/12039 %CUnited States %D1992 %GEnglish %2DOE/ER %1AC52-07NA27344 1992-03-05
