scipy.special.pbvv_seq(v, x)[source]

Parabolic cylinder functions Vv(x) and derivatives.

Parameters:
v : float

Order of the parabolic cylinder function

x : float

Value at which to evaluate the function and derivatives

Returns:
dv : ndarray

Values of V_vi(x), for vi=v-int(v), vi=1+v-int(v), …, vi=v.

dp : ndarray

Derivatives V_vi’(x), for vi=v-int(v), vi=1+v-int(v), …, vi=v.
