Numerical Differentiation
Functions
LUSE_ENGR701_704_NumericalMethods.Derivatives.endpoint — Method
endpoint(x, f, h, point[; method=:three])Find the derivative of a bookend point at either :begin or :end of dataset. Acceptable values for method include {:three, :five}.
LUSE_ENGR701_704_NumericalMethods.Derivatives.midpoint — Method
midpoint(x, f, h, point[; method=:three])Find the derivative of some point within a dataset. Acceptable values for method include {:three, :five, :2nd}.
LUSE_ENGR701_704_NumericalMethods.Derivatives.n1derivative — Method
n1derivative(x, f, j[; n=nothing])The general (n + 1)-point formula to approximate f' at point j.
Notes
If n = nothing, then entire dataset used to construct n'th Lagrange coefficient.
