darkhistory.utilities.hyp2f1_func_real

darkhistory.utilities.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:

ninteger

The order of \(_2F_1(1, n+1, n+2, x)\) to evaluate.

xndarray

The main argument of the function.

Returns:

ndarray

The result of \(_2F_1(1, n+1, n+2, x)\).
