d_func()

double complex d_func

(

double complex

x

)

Return first order derivative of the function.

\(f'(x)\)

{ return 2. * x; }

func()

double complex func

(

double complex

x

)

Return value of the function to find the root for.

\(f(x)\)

{
    return x * x - 3.; /* x^2 = 3 - solution is sqrt(3) */
    // return x * x - 2.; /* x^2 = 2 - solution is sqrt(2) */
}
