def _check_branch_cut(f, x0, dx, re_sign=1, im_sign=-1, sig_zero_ok=False, dtype=complex):

Check for a branch cut in a function.

Assert that x0 lies on a branch cut of function f and f is continuous from the direction dx.

Parameters

f : func
Function to check
x0 : array-like
Point on branch cut
dx : array-like
Direction to check continuity in
re_sign, im_sign : {1, -1}
Change of sign of the real or imaginary part expected
sig_zero_ok : bool
Whether to check if the branch cut respects signed zero (if applicable)
dtype : dtype
Dtype to check (should be complex)
