This is a short library that implements the complex-step derivative approximation algorithm for the computation of the N-derivative of an N-dimension function. This repository also includes the ...

A simple command line tool for calculating derivatives. This project was born as a low-effort challenge to take the mind off of more complicated stuff like compilers and virtual machines. Note that ...

Taylor series and asymptotic expansions are developed for $q$-extensions of the $p$-adic psi (derivative of log-gamma) function ``twisted'' by roots of unity ...

The input argument fun refers to an IML module that specifies a function that returns f, a vector of length m for least-squares subroutines or a scalar for other optimization subroutines. The returned ...

This is a preview. Log in through your library . This monthly journal, begun in 1950, is devoted entirely to research in pure and applied mathematics, principally to the publication of original papers ...
