treams.TMatrix.valid_points¶
- TMatrix.valid_points(grid, radii)¶
Points on the grid where the expansion is valid.
The expansion of the electromagnetic field is valid outside of the circumscribing spheres of each object. From a given set of coordinates mark those that are outside of the given radii.
- Parameters:
grid (array-like) – Points to assess. The last dimension needs length three and corresponds to the Cartesian coordinates.
radii (Sequence[float]) – Radii of the circumscribing spheres. Each radius corresponds to a position of the basis.
- Returns:
array
