RegularGridFiniteDifference

Defines a 1D finite difference over a regular grid

finite_difference_data: method

__init__(self, order, stencil=None, accuracy=4, end_point_accuracy=2, **kw): 

order: int

the order of the derivative to take
stencil: int | None

the number of stencil points to add
accuracy: int | None

the approximate accuracy to target with the method
end_point_accuracy: int | None

the extra number of stencil points to add to the end points
kw: Any

options passed through to the FiniteDifferenceMatrix

get_weights(m, s, n): 

Extracts the weights for an evenly spaced grid
