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 K_v(x,y)=x^v\Gamma(-v,x;xy)}

${\displaystyle K_{v}(x,y)=x^{v}\Gamma (-v,x;xy)}$

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

Semantic latex: K_v(x,y)=x^v\Gamma(-v,x;xy)

Confidence: 0

Mathematica

Translation: Subscript[K, v][x , y] == (x)^(v)* \[CapitalGamma][- v , x ; x*y]
