LaTeX to CAS translator

This mockup demonstrates the concept of TeX to Computer Algebra System (CAS) conversion.

The demo-application converts LaTeX functions which directly translate to CAS counterparts.

Functions without explicit CAS support are available for translation via a DRMF package (under development).

The following LaTeX input ...

{\displaystyle M_{\kappa,\mu}(z)}

${\displaystyle M_{\kappa ,\mu }(z)}$

... is translated to the CAS output ...

Wikitext context	{{short description\|In mathematics, a solution to a modified form of the confluent hypergeometric equation}} In mathematics, a '''Whittaker function''' is a special solution of '''Whittaker's equation''', a modified form of the [[confluent hypergeometric equation]] introduced by {{harvs\|txt\|authorlink=E. T. Whittaker\|last=Whittaker\|year=1904}} to make the formulas involving the solutions more symmetric. More generally, {{harvs\|txt\|authorlink=Hervé Jacquet\|last=Jacquet\|year1=1966\|year2=1967}} introduced Whittaker [[Function (mathematics)\|functions]] of [[reductive group]]s over [[local field]]s, where the functions studied by Whittaker are essentially the case where the local field is the real numbers and the group is SL<sub>2</sub>('''R'''). Whittaker's equation is :<math>\frac{d^2w}{dz^2}+\left(-\frac{1}{4}+\frac{\kappa}{z}+\frac{1/4-\mu^2}{z^2}\right)w=0.</math> It has a regular singular point at 0 and an irregular singular point at ∞. Two solutions are given by the '''Whittaker functions''' ''M''<sub>κ,μ</sub>(''z''), ''W''<sub>κ,μ</sub>(''z''), defined in terms of Kummer's [[confluent hypergeometric functions]] ''M'' and ''U'' by :<math>M_{\kappa,\mu}\left(z\right) = \exp\left(-z/2\right)z^{\mu+\tfrac{1}{2}}M\left(\mu-\kappa+\tfrac{1}{2}, 1+2\mu, z\right)</math> :<math>W_{\kappa,\mu}\left(z\right) = \exp\left(-z/2\right)z^{\mu+\tfrac{1}{2}}U\left(\mu-\kappa+\tfrac{1}{2}, 1+2\mu, z\right).</math> The Whittaker functions <math>M_{\kappa,\mu}(z)</math> and <math>W_{\kappa,\mu}(z)</math> are the same as those with opposite values of {{mvar\|μ}}, in other words considered as a function of {{mvar\|μ}} at fixed {{mvar\|κ}} and {{mvar\|z}} they are [[even function]]s. When {{mvar\|κ}} and {{mvar\|z}} are real, the functions give real values for real and imaginary values of {{mvar\|μ}}. These functions of {{mvar\|μ}} play a role in so-called [[Kummer space]]s.<ref>{{cite book\|title=Hilbert spaces of entire functions\|url=https://archive.org/details/hilbertspacesofe0000debr\|url-access=registration\|publisher=Prentice-Hall\|author=[[Louis de Branges]]\|asin=B0006BUXNM\|date=1968}} Sections 55-57.</ref> Whittaker functions appear as coefficients of certain representations of the group SL<sub>2</sub>('''R'''), called [[Whittaker model]]s. ==References== {{reflist}} {{AS ref \|13\|504\|14\|537}} {{citation\|first=Harry\|last=Bateman\|title=Higher transcendental functions\|volume=1\|year=1953\|publisher=McGraw-Hill\|url=http://apps.nrbook.com/bateman/Vol1.pdf}}. {{springer\|id=W/w097850\|title=Whittaker function\|first=Yu.A. \|last=Brychkov\|first2=A.P.\|last2= Prudnikov}}. {{dlmf\|first=Adri B.
