Cannot run the matlab GUIDE

I cannot run the guide in Matlab, even a blank guide.
When I created a blank guide and run it(blank guide),the guide cannot run a prompt appeared like below:
??? Operands to the || and && operators must be convertible to logical scalar values.

Error in ==> gui_mainfcn at 78
    if (numargin>1 && ishghandle(varargin{2}))

Error in ==> openfig at 42
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

Error in ==> gui_mainfcn>local_openfig at 286
    gui_hFigure = openfig(name, singleton, visible);

Error in ==> gui_mainfcn at 159
        gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt,
        gui_Visible);

Error in ==> openfig at 42
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

Error in ==> gui_mainfcn>local_openfig at 286
    gui_hFigure = openfig(name, singleton, visible);

Error in ==> gui_mainfcn at 159
        gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt,
        gui_Visible);

Error in ==> fractal1 at 42
    gui_mainfcn(gui_State, varargin{:});

I just opened openfig.m from release R2010b and line 42 of that function
does NOT match what you've posted here. I suspect that you've created your
own openfig.m function and that it is shadowing the version of that function
that shipped with MATLAB. If so, remove or rename your openfig.m function.
To confirm this, use the command:

which -all openfig

You should see one instance, that being the openfig.m in the
toolbox/matlab/graphics subdirectory underneath the root MATLAB directory
for your installation. Any others in that list should be renamed or
removed.
