1. In demo.m:

Error in demo (line 32)
I_gw = out_of_gamut_clipping(reshape(reshape(im2double(I),[],3) * ...

Unrecognized function or variable 'phi'.

Error in demo (line 39)
reshape(phi(reshape(I,[],3)) * M,[sz(1),sz(2),sz(3)]));

2. in gui\main.m :
   Unrecognized function or variable 'PHI'.

Error in main>autoWB_Callback (line 95)
reshape(PHI(reshape(I,[],3)) * M,[sz(1),sz(2),sz(3)]));

Error in gui_mainfcn (line 95)
feval(varargin{:});

Error in main (line 28)
gui_mainfcn(gui_State, varargin{:});
