ikeda_carpenter returns the value of the Ikeda-Carpenter function:

f = 0.5 * (alpha**3)*((1-R)*(x**2)*exp(-alpha*x)+2*R*beta*(1/alpha**3)*(exp(-beta*x)-exp(-alpha*x)*(1+(1+0.5*x*alpha**3)*x*alpha**3)))

r = ikeda_carpenter(x : float,alpha : float,beta : float,R : float)

Variable	Type	Description
x	float	Value at which the function is evaluated.
alpha	float	Function parameter
beta	float	Function parameter
R	float	Function parameter
r	tuple	The tuple returned by the function. r[0] : int, error code. If non-zero, an error has occurred. r[1] : str, error message. r[2]: float, value of the function at x.
