Hi Shubham, What are you trying to plot? Are you trying to plot the surface

z=x^2+y^2 ?

How about:

ezsurf('x^2+y^2')
shading interp;

It is always a good idea not to state only, that there is an error, but paste a copy of the message. Matlab's error messages are meaningful and help you and us to identify your problem.

Kind regards, Jan
