Analysis Numerica

Quamquam bene est problemata exacte solvere, potest melius esse approximationem habere, si celerius computari potest.

Historia

Analysis Numerica — Tabula argillacea Babylonica, c. 1800-1600 a.C.n. Magnitudo lateris quadratae est 30. Prope diagonalem sunt numeri (1, 24, 51, 10) et (42, 25, 35), hoc est 1 + 24/60 + 51/60² + 10/60³ = 1.414213... vel fere ${\sqrt {2}}$ , et 42 + 25/60 + 35/60² = 42.426388..., qui est (paene) magnitudo diagonalis quadratae.

Periti Babylonici numeros irrationales calculabant cum diagonales quadratas mensurarent. Sciebant aequationes quadraticas resolvere et magnitudines laterum figurarum regularium calculare.

Aegypti quoque quantitates irrationales calculabant.

Quamquam Babyloni et Aegypti algorithmos habebant et sciebant calculare, mathematici Graeci regulas generales invenerunt, et demonstraverunt has regulas correctas esse.

Mathematici hodierni non solum theoremata sed etiam methodos numericas inveniunt. Isaacus Newtonus algorithmum proponit ad integrale approximandum. Carolus Fridericus Gauss plurimos algorithmos numericos creavit.

Computatris potest plura et celerius calculare.

Algorithmi magni momenti

Methodus Newtoni ad integrum approximandum
Eliminatio Gaussiania, ad matricem invertendam
Algorithmus "simplex" appellatus, qui invenit valorem optimum qui resolvit aequationes et inaequationes linearium
Transformatio Fourierana
