Callable) – The vector field function.
ndarray) – A (n_cell x n_dim) matrix of coordinates where the potential function is evaluated.
Callable]) – function that returns the Jacobian of the vector field function evaluated at a particular point.
ndarray]) – Diffusion matrix. It must be a square matrix with size corresponds to the number of columns (features) in the X matrix.
A matrix storing the x-coordinates on the two-dimesional grid. U: A matrix storing the potential value at each position. P: Steady state distribution or the Boltzmann-Gibbs distribution for the state variable. vecMat: List velocity vector at each position from X. S: List of constant symmetric and semi-positive matrix or friction (dissipative) matrix, corresponding to the divergence part,
at each position from X.
- A: List of constant antisymmetric matrix or transverse (non-dissipative) matrix, corresponding to the curl part, at each position
