X (
ndarray
) – A matrix storing the x-coordinates on the two-dimesional grid.U (
ndarray
) – A matrix storing the potential value at each position.P (
ndarray
) – Steady state distribution or the Boltzmann-Gibbs distribution for the state variable.vecMat (list) – List velocity vector at each position from X.
S (list) – List of constant symmetric and semi-positive matrix or friction matrix, corresponding to the divergence part, at each position from X.
A (list) – List of constant antisymmetric matrix or transverse matrix, corresponding to the curl part, at each position from X.
