Metríc3 is a project developed in Python, compatible with any Linux operating system. It is responsible for performing calculations of Christoffel symbols, the Riemann tensor, the Ricci tensor, and the scalar curvature.
The distinctive features of this project include that, for performing the aforementioned calculations, it utilizes a user interface that allows explicit input of the metric tensor. For displaying results, it uses LaTeX to construct a PDF document containing the calculation results in mathematical language and organized in matrix form.
Below is a gif where you can see how the program works and the way it shows the results of the calculations.
For more information about its use or installation, we invite you to consult the documentation available in English or Spanish.
