Error using corr2 Expected input number 1, A, to be two-dimensional.

Error in corr2>ParseInputs (line 35) validateattributes(A, {'logical' 'numeric'}, {'real','2d'}, mfilename, 'A', 1);

Error in corr2 (line 21) [a,b] = ParseInputs(varargin{:});

Error in number_plate_det (line 60) y=corr2(imgfile{1,k},n1);

what is size of imgfile{1,k} and n1?

I suspect you are inputting the filename.

You cannot use corr2() with RGB images.
