Double click on the block and change the output color space option to "grayscale" if you can. Or, the Computer Vision Toolbox offers a Color Space Conversion block. Or, use a MATLAB function block to wrap the rgb2gray in Simulink, this is part of basic MATLAB. Or just do it your self, since intensity of RGB is just sqrt(R^2 + G^2 + B^2).
