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_n(x,\beta,\gamma) = \sum_{k=0}^n (-1)^k{n \choose k}{x\choose k}k!(x+\beta)_{n-k}\gamma^{-k}}
... is translated to the CAS output ...
Semantic latex: M_n(x , \beta , \gamma) = \sum_{k=0}^n(- 1)^k{n \choose k}{x\choose k} k! \Pochhammersym{x + \beta}{n-k} \gamma^{-k}

Translation: Subscript[M, n][x , \[Beta], \[Gamma]] == Sum[(- 1)^(k)*Binomial[n,k]*Binomial[x,k]*(k)!*Pochhammer[x + \[Beta], n - k]*\[Gamma]^(- k), {k, 0, n}, GenerateConditions->None]
Information
Sub Equations
- Subscript[M, n][x , \[Beta], \[Gamma]] = Sum[(- 1)^(k)*Binomial[n,k]*Binomial[x,k]*(k)!*Pochhammer[x + \[Beta], n - k]*\[Gamma]^(- k), {k, 0, n}, GenerateConditions->None]
Free variables
- \[Beta]
- \[Gamma]
- n
- x
Symbol info
- Could be the Euler-Mascheroni constant.
But it is also a Greek letter. Be aware, that this program translated the letter as a normal Greek letter and not as a constant! Use the DLMF-Macro \EulerConstant to translate \gamma as a constant.
- Function without DLMF-Definition. We keep it like it is (but delete prefix \ if necessary).
- 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
