function value = c8_norm_l2 ( x ) %*****************************************************************************80 % %% C8_NORM_L2 evaluates the L2 norm of a C8. % % Discussion: % % Numbers of equal norm lie on circles centered at (0,0). % % The L2 norm can be defined here as: % % C8_NORM_L2(X) = sqrt ( ( real (X) )**2 + ( imag ( X ) )**2 ) % % Licensing: % % This code is distributed under the GNU LGPL license. % % Modified: % % 13 September 2006 % % Author: % % John Burkardt % % Parameters: % % Input, complex X, the value whose norm is desired. % % Output, real VALUE, the 2-norm of X. % value = sqrt ( ( real ( x ) ).^2 + ( imag ( x ) ).^2 ); return end
