hyp2f1_func_real
(n, x)¶ Returns the real part of \(_2F_1(1, n+1, n+2, x)\).
Avoids the need for complex numbers in
scipy.special.hyp2f1
, which is very slow. The function definition is identical.Parameters: - n : integer
The order of \(_2F_1(1, n+1, n+2, x)\) to evaluate.
- x : ndarray
The main argument of the function.
Returns: - ndarray
The result of \(_2F_1(1, n+1, n+2, x)\).
