real time point tracking and confining it within a predefined boundary

hi everyone, i need a matlab code to track any point in a 2 dimensional plane and not allowing it to cross a predefined boundary. The boundary,for example, can be defined by x and y coordinates which may be predefined or entered by the user. The point is to move randomly and stay inside that boundary.

Thanks

This forum won't just send you MATLAB code without you showing us what you've done so far (as this sounds a bit like homework). To get you started, though, check out
