There are two vectors that will make an xy-plane. I want to draw a peak pointing in z-direction on a desired location on the xy-plane. In code form it is:

x=linspace(0,180,100);% 1st vector
y=x;% 2nd vector

Now I want to draw a peak of strenght 5 on the intersection of the point (x1,y1)=(30,50).Likewise, I want to draw another peak on the intersection of the point (x2,y2)=(40,120). Further, I want to draw another peak on the intersection of the point (x3,y3)=(60,140). But this whole plot should be a 3D plot as shown in the attached image.

What determines the z-valeus everywhere where there isn't a peak?

Thank you for your response. There is no eq. but I want to draw peaks of my desired values. Say for example, one peak should be of height 5, another should be of height 5.5 and another should be of height 7.
