I'm trying to run this file on CentOS. I tried to simply run the GUI by typing "viewer3d" (no quotes) into the command window while in the correct directory. I get the following error messages:

??? Undefined function or method 'imshow' for input arguments of type 'uint8'.

Error in ==> menubar>CreatMenuBar at 181
    data.menuitems(i).HandleImshow=imshow(barimage,'Parent',data.menuitems(i).Handle);

Error in ==> menubar>UpdateMenu at 353
    CreatMenuBar(uimenuhandle,datahandle,Pos,figure_handle)

Error in ==> menubar at 83
    UpdateMenu(datahandle,figure_handle);

Error in ==> viewer3d>addWindows at 3098
data=addWindowsMenus(data);

Error in ==> viewer3d>viewer3d_OpeningFcn at 155
data=addWindows(data);

Error in ==> gui_mainfcn at 221
    feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in ==> viewer3d at 47
    gui_mainfcn(gui_State, varargin{:});

I also tried working with some of the example data. I typed in the command that the help file suggests:

load('ExampleData\CommandlineData.mat');
    viewer3d(V);

And I get more errors: ??? Error using ==> load
Unable to read file ExampleData\CommandlineData.mat: No such file or directory.

I'm very confused. I'm definitely working in the right directory. Any insight?
