Oblate spheroidal angular function of the first kind and its derivative

Computes the oblate sheroidal 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.

Returns :

s :

Value of the function

sp :

Value of the derivative vs x
