Estimation of organic Carbon is done by means of linear regressions on log(organic carbon) ~ log(organic matter). It gives back a organic carbon value for each organic matter value provided. If there …

@epolack and @LaurentVidal95 need support for multicomponent (psi(x) is a vector) for twisted bilayer graphene
It would also be nice to have for
- non collinear spin
- solving maxwell equations (…

It would be nice to have a simplified interface for a general linear constant coefficient PDE of the form `du/dt + A*du/dx + B*du/dy + C*du/dz = f` where the matrices A, B, C are specified. Assuming c…

It's not clear to me if the issue seems to be with the package EinsteinPy or with SymPy itself.
I am unable to evaluate the Ricci and Einstein tensors for a specific metric. The same error occurs i…

Observed problem:
Although providing a negative `BASE_DENSITY` is not possible this can easily be circumvented by defining a negative `densityRatio`. Same for mass.
Both cases result in a running co…

## Reason
Cold magnetized plasma wave calculations utilize a tensor for the electric conductivity (Stix tensor), while applications like Ferret require d**P**/dt and d**M**/dt (time derivatives of t…
