Question

Please help me with these plots!!

Write a Matlab program that asks the user to enter a positive number a between 2 and 10. Then create x and y vectors from -a to +a with spacing 0.05. Use the meshgrid function to map x and y onto two new two-dimensional arrays called X and Y. Use your new arrays to calculate the vector Z, with magnitude Z = X2 + Y2 exp (-X2 -Y2) Using the subplot function, generate the following 3D plots on one page: Use the plot3 function to create a three-dimensional plot of Z. Use the mesh function to create a three-dimensional plot of Z. Use the surf function to create a three-dimensional plot of Z. Use the contour function to create a three-dimensional plot of Z. Don't forget to label your axes and title your plots appropriately.

Explanation / Answer

aTEMP = input('Please input a number between 2 and 10 ', 's'); %User GIves Input In String

a = str2double(aTEMP); %String Converted to Double Integer

x = -a:0.05:a;

y = x;

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

Z = (sqrt(X^2 + Y^2))*exp(-(X^2 + Y^2));

subplot(2,2,1)

plot3(X,Y,Z); %Part (a)

xlabel('X');

ylabel('Y');

zlabel('Z');

grid on

subplot(2,2,2)

mesh(X,Y,abs(Z)); %Part (b)

xlabel('X');

ylabel('Y');

zlabel('Z');

grid on

subplot(2,2,3)

surf(X,Y,abs(Z)); %Part (c)

xlabel('X');

ylabel('Y');

zlabel('Z');

grid on

subplot(2,2,4)

contour(X,Y,Z); %Part (d)

xlabel('X');

ylabel('Y');

zlabel('Z');

grid on
