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 \frac{d^2 S}{dz^2}+\left(\sum _{j=1}^N \frac{\gamma _j}{z - a_j} \right) \frac{dS}{dz} + \frac{V(z)}{\prod _{j=1}^N (z - a_j)}S = 0}
... is translated to the CAS output ...
Semantic latex: \deriv [2]{S}{z} +(\sum_{j=1}^N \frac{\gamma _j}{z - a_j}) \frac{dS}{dz} + \frac{V(z)}{\prod _{j=1}^N (z - a_j)} S = 0

Translation: D[S, {z, 2}]+(Sum[Divide[Subscript[\[Gamma], j],z - Subscript[a, j]], {j, 1, N}, GenerateConditions->None])*Divide[d*S,d*z]+Divide[V[z],Product[z - Subscript[a, j], {j, 1, N}, GenerateConditions->None]]*S == 0
Information
Sub Equations
- D[S, {z, 2}]+(Sum[Divide[Subscript[\[Gamma], j],z - Subscript[a, j]], {j, 1, N}, GenerateConditions->None])*Divide[d*S,d*z]+Divide[V[z],Product[z - Subscript[a, j], {j, 1, N}, GenerateConditions->None]]*S = 0
Free variables
- N
- S
- Subscript[\[Gamma], j]
- Subscript[a, j]
- d
- z
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.
- Derivative; Example: \deriv[n]{f}{x}
Will be translated to: D[$1, {$2, $0}] Relevant links to definitions: DLMF: http://dlmf.nist.gov/1.4#E4 Mathematica: https://reference.wolfram.com/language/ref/D.html
- Function without DLMF-Definition. We keep it like it is (but delete prefix \ if necessary).
