scipy.special.kelvin(x) = <ufunc 'kelvin'>

Kelvin functions as complex numbers

Returns :

Be, Ke, Bep, Kep :

The tuple (Be, Ke, Bep, Kep) contains complex numbers representing the real and imaginary Kelvin functions and their derivatives evaluated at x. For example, kelvin(x)[0].real = ber x and kelvin(x)[0].imag = bei x with similar relationships for ker and kei.
