Question
Write a Matlab program that asks the user to enter the seven digits of the z-number and define the positive number a as the range (difference between the maximum and minimum) of z . 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= sin(sqrt((x2+y2)))
Use the subplot function to generate the following 3D plots on one page:
(a) Use the plot3 function to create a three-dimensional plot of Z.
(b) Use the mesh function to create a three-dimensional plot of Z.
(c) Use the surf function to create a three-dimensional plot of Z.
(d) Use the contour function to create a three-dimensional plot of Z.
(e) Generate a combination of surface and contour plot of Z.

Explanation / Answer
v1=input('Enter 1st number: ');
v2=input('Enter 2nd number: ');
v3=input('Enter 3rd number: ');
v4=input('Enter 4th number: ');
v5=input('Enter 5th number: ');
v6=input('Enter 6th number: ');
v7=input('Enter 7th number: ');
z=[v1,v2,v3,v4,v5,v6,v7];
a=max(z)-min(z);
x=-a:0.05:a;
y=-a:0.05:a;
[X Y]=meshgrid(x,y);
f=@(X,Y) sin(sqrt(X.^2+Y.^2));
Z=f(X,Y);
%plot3(X,Y,Z)
subplot(2,3,1)
plot3(X,Y,Z);
