Matlab R2011b mex file compilation error "Unrecognized switch: -argcheck"

When i try to compile mex files at matlab r2011b it gives an error as below.

How can i fix it?

I downloaded codes from http://www.timotheecour.com/software/ncut_multiscale/ncut_multiscale.html and compile

my system: core i7 - 64bit win7

You can change your home, image, and results directories if you want ; see startup/definePaths

        MEX [option1 ... optionN] sourcefile1 [... sourcefileN]
            [objectfile1 ... objectfileN] [libraryfile1 ... libraryfileN]

    Use the -help option for more information, or consult the MATLAB API Guide.

-argcheck option for mex is removed from MATLAB R2010b. Which version of MATLAB are you using? You can safely remove this option if you think your mex files do not expect to have invalid calls to API functions. For example calling mxGetPr with a NULL pointer would crash. "-argcheck" would catch this and throw as an error.
