I tried

x= linspace(0, 5);

y= linspace(-4, 1);

z= x + y - (x.^2 + y.^2);

[X,Y] = meshgrid(x,y); surf(X,Y,z)

when I run it, I get this error 'Z must be a matrix, not a scalar or vector.' in surf. I don't think I'm setting x and y correctly.

A. Write a MATLAB script surfaceplot.m that plots the following surface Z for 0 S x, y
