41Digamma function — For Barnes s gamma function of 2 variables, see double gamma function. Digamma function ψ(s) in the complex plane. The color of a point s encodes the value of ψ(s). Strong colors denote values close to zero and hue encodes the value s argument …
42Laguerre polynomials — In mathematics, the Laguerre polynomials, named after Edmond Laguerre (1834 ndash; 1886), are the canonical solutions of Laguerre s equation::x,y + (1 x),y + n,y = 0,which is a second order linear differential equation.This equation has… …
43Generalized minimal residual method — In mathematics, the generalized minimal residual method (usually abbreviated GMRES) is an iterative method for the numerical solution of a system of linear equations. The method approximates the solution by the vector in a Krylov subspace with… …
44Jacobsthal number — In mathematics, the Jacobsthal numbers are an integer sequence named after the German mathematician Ernst Jacobsthal. Like the related Fibonacci numbers, they are a specific type of Lucas sequence Jacobsthal numbers are the type for which P = 1,… …
45Bernoulli number — In mathematics, the Bernoulli numbers Bn are a sequence of rational numbers with deep connections to number theory. They are closely related to the values of the Riemann zeta function at negative integers. There are several conventions for… …
46Quicksort — Infobox Algorithm class=Sorting algorithm Quicksort in action on a list of numbers. The horizontal lines are pivot values. data=Varies time=O(nlog n) on average space=Varies by implementation optimal=Sometimes Stability= [Sorting… …
47Merge sort — Example of merge sort sorting a list of random dots. Class Sorting algorithm Data structure Array Worst case performance O(n log n) …
48Generating function — This article is about generating functions in mathematics. For generating functions in classical mechanics, see Generating function (physics). For signalling molecule, see Epidermal growth factor. In mathematics, a generating function is a formal …
49Multiset — This article is about the mathematical concept. For the computer science data structure, see Set (computer science)#Multiset. In mathematics, the notion of multiset (or bag) is a generalization of the notion of set in which members are allowed to …
50Secant method — In numerical analysis, the secant method is a root finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f .The methodThe secant method is defined by the recurrence relation:x {n+1} = x n… …
