(x, x0, M=1)[source][source]¶ Return finite difference weights_and_points for derivatives of all orders.
Parameters: x : vector, length n
x-coordinates for grid points
x0 : scalar
location where approximations are to be accurate
m : scalar integer
highest derivative that we want to find weights_and_points for
Returns: C : array, shape n x m+1
contains coefficients for the j’th derivative in column j (0 <= j <= m)
