Question

1. In MATLAB, generate a 3D plot as follows:

1. Create 2 vectors x and y, both ranging from -5 to 5 with interval of 0.05 using linspace or colon operator.

2. Generate grid of values X and Y using the vectors x and y.

3. Define the variable Z as follows:

Z = 2X3 + 4Y2 + 7 +sinX3 + Y2

4. Generate a surface and a mesh plot with the variables X,Y,Z. Show your plots.

Answer 1

clc;

x = -5:0.05:5;

y = -5:0.05:5;

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

Z = 2*X.^3 + 4*Y.^2 + 7*sin(x).^3 + Y.^2;

figure()

surf(X,Y,Z)

figure()

mesh(X,Y,Z)
