i am learning MATLAB, but have not yet learned anything do do with graphing, but need a program that can plot x.y.z graphs for my calculus work,

can someone please help me plot 3d graphs on MATLAB, for example

z=x²+2x+y²-y

how can i input x,y,z so that MATLAB will give me the surface graph of this function
