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 \Phi_{n+1}(z)=z\Phi_n(z)-\overline\alpha_n\Phi_n^*(z)}
... is translated to the CAS output ...
Semantic latex: \Phi_{n+1}(z) = z \Phi_n(z) - \conj{\alpha}
Confidence: 0.78713822532466

Translation: Subscript[\[CapitalPhi], n + 1][z] == z*Subscript[\[CapitalPhi], n][z]- Conjugate[\[Alpha]]
Information
Sub Equations
- Subscript[\[CapitalPhi], n + 1][z] = z*Subscript[\[CapitalPhi], n][z]- Conjugate[\[Alpha]]
Free variables
- Subscript[\[CapitalPhi], n + 1]
- Subscript[\[CapitalPhi], n]
- \[Alpha]
- n
- z
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.
- Function without DLMF-Definition. We keep it like it is (but delete prefix \ if necessary).
- Conjugate complex number; Example: \conj{z}
Will be translated to: Conjugate[$0] Relevant links to definitions: DLMF: http://dlmf.nist.gov/1.9#E11 Mathematica: https://reference.wolfram.com/language/ref/Conjugate.html
