WebAug 27, 2024 · Additional Notes. This function is the equivalent of trapz and cumtrapz for numerical differentiation and is especially useful for estimating derivatives where the underlying function is unknown (i.e. we have some data set vs. that describes a function , but this underlying function is unknown and so we use the data set to approximate its ... 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.
