public function jac_intr(u, du)

Arguments

Type IntentOptional AttributesName
real(kind=r8), intent(in), dimension(:,:):: u

The state vector for the system of differential equations, and its derivatives, for which the Jacobian should be evaluated. Column represents the derivative.
real(kind=r8), intent(in), dimension(:,:):: du

The state vector for the system of differential equations, and its derivatives, which the Jacobian operates on. Column represents the derivative.

Return Value real(kind=r8), dimension(size(u,1))

Description

An interface for the product of the Jacobian of the (nonlinear) right-hand-side of an ODE and another vector.
