# scipy.special.obl_ang1_cv¶

scipy.special.obl_ang1_cv(m, n, c, cv, x) = <ufunc 'obl_ang1_cv'>

Oblate spheroidal angular function obl_ang1 for precomputed characteristic value

Computes the oblate spheroidal angular function of the first kind and its derivative (with respect to x) for mode parameters m>=0 and n>=m, spheroidal parameter c and |x| < 1.0. Requires pre-computed characteristic value.

Returns
s

Value of the function

sp

Value of the derivative vs x
