Derivative algorithm
WebThe complex-step derivative approximation is a very convenient way of estimating derivatives numerically. It is a simple and accurate means of finding derivatives of a quantity calculated by an existing algorithm. If f is the result of any (real-valued) numerical algorithm, and x is one of the input variables, then the derivative ∂f/∂x is ... Their algorithm is applicable to higher-order derivatives. A method based on numerical inversion of a complex Laplace transform was developed by Abate and Dubner. An algorithm that can be used without requiring knowledge about the method or the character of the function was developed by … See more In numerical analysis, numerical differentiation algorithms estimate the derivative of a mathematical function or function subroutine using values of the function and perhaps other knowledge about the function. See more An important consideration in practice when the function is calculated using floating-point arithmetic of finite precision is the choice of step size, h.
