How to plot peaks on desired location in a 3D plot?
6 views (last 30 days)
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.

[X,Y] = ndgrid(0:300);
C = 50:100:300;
Zf = @(C) exp(-(((X-C).^2)*0.5+((Y-C).^2)));
Z = Zf(C(1)) + Zf(C(2)) + Zf(C(3));
[pks,locs] = findpeaks(Z(:), 'MinPeakHeight',0.5)
surf(X, Y, Z, 'EdgeColor','none')
plot3(X(locs), Y(locs), Z(locs), '^r')
Experiment with your data with this approach.
