Hi Vitaly,
here's the first real issue we encountered when using feynson with linear propagators: applying symmetrize to
```
{{{l1^2, l1^2 + 2*gammakin*l1*me*np - 2*gammakin*me^2*u0b - l1*me*nm…

Recently, we have been using STRUMPACK to solve the system of linear equations, which is a sparse matrix with a scale of 300000 x 300000, and it will be solved for 200 iterations. In each iteration, t…

I just ran into a case that grid sizing ought to be able to deal with, but apparently cannot.

The functions to invert a matrix or solve a system of linear equations such as `solve`, `solve_left`, or `inv` currently throw an unspecific `ErrorException`. For example:
```
julia> M = matrix(ZZ…

Hi,
I am new to SymPy and trying to solve a parametric linear system with 4 variables x1, x2, x3, x4 and 4 parameters a, b, i, and j. The system is under-determined, it has 1 free variable despite th…

Hi, thank you so much for StemCStudio and your videos building and explaining geometric Algebra.
I discovered this technique this Summer and it is tremendously simpler and more intuitive than Tensor…
