conatus.contour.CountResult¶

class conatus.contour.CountResult(count, winding, poles, region, operator, evaluations, smallest_step, smallest_at, winding_error, phase_step, control='', log=<factory>)[source]¶

Bases: object

Number of eigenvalues of T(z) in a region, by the argument principle (count()).

Parameters:

count (int | None)
winding (int)
poles (int | None)
region (ContourBox)
operator (str)
evaluations (int)
smallest_step (float)
smallest_at (complex)
winding_error (float)
phase_step (float)
control (str)
log (list[str])
