orbithunter.OrbitKS.matvec

OrbitKS.matvec(other, **kwargs)

Matrix-vector product of a vector with the Jacobian of the current state.

Parameters

otherOrbitKS

OrbitKS instance whose state represents the vector in the matrix-vector multiplication.

kwargsdict

Included to match Orbit signature

Returns

OrbitKS :

OrbitKS whose state and other parameters result from the matrix-vector product.

Notes

Equivalent to computation of v_t + v_xx + v_xxxx + d_x (u .* v), where v is the state of ‘other’.
