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 \begin{align} C_0^\alpha(x) & = 1 \\ C_1^\alpha(x) & = 2 \alpha x \\ C_n^\alpha(x) & = \frac{1}{n}[2x(n+\alpha-1)C_{n-1}^\alpha(x) - (n+2\alpha-2)C_{n-2}^\alpha(x)]. \end{align} }
... is translated to the CAS output ...
Semantic latex: \begin{align} C_0^\alpha(x) & = 1 \\ C_1^\alpha(x) & = 2 \alpha x \\ C_n^\alpha(x) & = \frac{1}{n}[2x(n+\alpha-1)C_{n-1}^\alpha(x) - (n+2\alpha-2)C_{n-2}^\alpha(x)]. \end{align}

Translation: (Subscript[C, 0])^\[Alpha][x] == 1 (Subscript[C, 1])^\[Alpha][x] == 2*\[Alpha]*x (Subscript[C, n])^\[Alpha][x] == Divide[1,n]*(2*x*(n + \[Alpha]- 1)*(Subscript[C, n - 1])^\[Alpha][x]-(n + 2*\[Alpha]- 2)*(Subscript[C, n - 2])^\[Alpha][x])
Information
Sub Equations
- (Subscript[C, 0])^\[Alpha][x] = 1
- (Subscript[C, 1])^\[Alpha][x] = 2*\[Alpha]*x
- (Subscript[C, n])^\[Alpha][x] = Divide[1,n]*(2*x*(n + \[Alpha]- 1)*(Subscript[C, n - 1])^\[Alpha][x]-(n + 2*\[Alpha]- 2)*(Subscript[C, n - 2])^\[Alpha][x])
Free variables
- \[Alpha]
- n
- x
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).
