Function electro::finite_diff_rect

pub fn finite_diff_rect(pot_mat: &Matrix<f64>) -> Result<Matrix<f64>, Error>

Computes the potential over a grid represented by a field matrix using a finite difference approximation to Poisson's equation. Takes as input a matrix representing the physical grid you're modeling, with known starting values (or zero).

Returns a Matrix of the same dimensions with the potentials computed.
