A call to nag_dae_ivp_dassl_linalg (d02npc) specifies that the Jacobian to be used is banded in structure. If nag_dae_ivp_dassl_linalg (d02npc) is not called before a call to nag_dae_ivp_dassl_gen (d02nec) then the Jacobian is assumed to be full.
neq – IntegerInput
On entry: the number of differential-algebraic equations to be solved.
ml – IntegerInput
the number of subdiagonals in the band.
mu – IntegerInput
the number of superdiagonals in the band.
