Question

Plot the surface generated by z = 3x2 + 2y2 - 10 in the intervals -4 ≤ x ≤ 4 and -3 ≤ y ≤ 3 using mesh or surf commands and chose an increment of 0.1. Label the x-, y-, and z-axes as “X”, “Y”, and “Z.” Include a title of the plot (In_Class Assignment – Problem 1). Save the plot as Problem 1. Hint: Use semicolons to prevent Matlab from showing the large matrices or vectors.

Answer 1

MatLab program

clear
clc
% x and y using mesh grid command
[x,y]=meshgrid(-4:0.1:4,-3:0.1:3);
% z as given function of x,y
z=3*x.^2+2*y.^2-10;
% ploting the surface
surf(x,y,z)
xlabel('X')
ylabel('Y')
zlabel('Z')
title('In Class Assignment - Problem 1')

Save the above program and execute it.
