Plotting two functions on 3D surface for the same interval

Hello

I have two functions, say

Z1=x^2

Z2=x^3

x: 0:10

How i can create a 3D surface plot

thanks in advance

Answer 1

Try this:

x = 0:10;
Z1=x.^2;
Z2=x.^3;

figure
surf(Z1.'*Z2)

Another possibility:

figure
surf([Z1; Z2])

It is not certain what you want.

many thanks to you dear Star Strider

I need to put

x: on the x-axis

Z1: on the y-axis

Z2: on the z-axis

How I can name the axis

thanks Dear Star Strider

[Star Strider]

As always, my pleasure!

Try this:

figure
surf(x, Z1, ones(size(x(:)))*Z2)
xlabel('x')
ylabel('Z1')
zlabel('Z2')

why is the scale on the x-axis on the plot does not fit the given interval x:0:10

[Star Strider]

It should with the code I just posted.

Dear Star Strider

one last question..

How i can give a different color for each function

i mean

color for Z1 and another color for Z2

i will be greatfull for you

regards

[Star Strider]

That is not possible as you have defined the plot.

The ‘x’ and ‘Z1’ vectors define the axes, so only ‘Z2’ can have color associated with the surface plot.
