function value = g ( u ) %*****************************************************************************80 % %% G evaluates the outward normal values assigned at Neumann boundary conditions. % % Discussion: % % This routine must be changed by the user to reflect a particular problem. % % Modified: % % 25 February 2004 % % Parameters: % % Input, real U(N,M), contains the M-dimensional coordinates of N points. % % Output, VALUE(N), contains the value of outward normal at each point % where a Neumann boundary condition is applied. % value = zeros ( size ( u, 1 ), 1 ); return end
