LaTeX to CAS translator

Jump to navigation Jump to search

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 (s)_n = s (s+1)\cdots (s+n-1)}

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

Semantic latex: \Pochhammersym{s}{n} = s(s + 1) \cdots(s + n - 1)

Confidence: 0.90733333333333

Mathematica

Translation: Pochhammer[s, n] == s*(s + 1) \[Ellipsis](s + n - 1)

Information

Sub Equations

  • Pochhammer[s, n] = s*(s + 1) \[Ellipsis](s + n - 1)

Free variables

  • n
  • s

Symbol info

  • Pochhammer symbol; Example: \Pochhammersym{a}{n}

Will be translated to: Pochhammer[$0, $1] Relevant links to definitions: DLMF: http://dlmf.nist.gov/5.2#iii Mathematica: https://reference.wolfram.com/language/ref/Pochhammer.html
