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 \int_{-1}^1 C_n^{(\alpha)}(x)C_m^{(\alpha)}(x)(1-x^2)^{\alpha-\frac{1}{2}}\,dx = 0.}
... is translated to the CAS output ...
Semantic latex: \int_{-1}^1 \ultrasphpoly{\alpha}{n}@{x} \ultrasphpoly{\alpha}{m}@{x}(1 - x^2)^{\alpha-\frac{1}{2}} \diff{x} = 0
Confidence: 0.6805

Translation: Integrate[GegenbauerC[n, \[Alpha], x]*GegenbauerC[m, \[Alpha], x]*(1 - (x)^(2))^(\[Alpha]-Divide[1,2]), {x, - 1, 1}, GenerateConditions->None] == 0
Information
Sub Equations
- Integrate[GegenbauerC[n, \[Alpha], x]*GegenbauerC[m, \[Alpha], x]*(1 - (x)^(2))^(\[Alpha]-Divide[1,2]), {x, - 1, 1}, GenerateConditions->None] = 0
Free variables
- \[Alpha]
- m
- n
Symbol info
- Could be the second Feigenbaum constant.
But this system doesn't know how to translate it as a constant. It was translated as a general letter.
- Ultraspherical Gegenbauer polynomial; Example: \ultrasphpoly{\lambda}{n}@{x}
Will be translated to: GegenbauerC[$1, $0, $2] Relevant links to definitions: DLMF: http://dlmf.nist.gov/18.3#T1.t1.r3 Mathematica: https://reference.wolfram.com/language/ref/GegenbauerC.html
