Purpose
CVDenseJacFn - type for user provided dense Jacobian function.
Synopsis
This is a script file.
Description
CVDenseJacFn - type for user provided dense Jacobian function.
IVP Problem
The function DJACFUN must be defined as
FUNCTION J = DJACFUN(T,Y,FY)
and must return a matrix J corresponding to the Jacobian of f(t,y).
The input argument FY contains the current value of f(t,y).
If a user data structure DATA was specified in CVodeMalloc, then
DJACFUN must be defined as
FUNCTION [J, NEW_DATA] = DJACFUN(T,Y,FY,DATA)
If the local modifications to the user data structure are needed in
other user-provided functions then, besides setting the matrix J,
the DJACFUN function must also set NEW_DATA. Otherwise, it should
set NEW_DATA=[] (do not set NEW_DATA = DATA as it would lead to
unnecessary copying).
Adjoint Problem
The function DJACFUNB must be defined either as
FUNCTION JB = DJACFUNB(T,Y,YB,FYB)
or as
FUNCTION [JB, NEW_DATA] = DJACFUNB(T,Y,YB,FYB,DATA)
depending on whether a user data structure DATA was specified in
CVodeMalloc. In either case, it must return the matrix JB, the
Jacobian of fB(t,y,yB), with respect to yB. The input argument
FYB contains the current value of f(t,y,yB).
See also CVodeSetOptions
NOTE: DJACFUN and DJACFUNB are specified through the property
JacobianFn to CVodeSetOptions and are used only if the property
LinearSolver was set to ’Dense’.
