how do i get x,y and z co-ordinates of the peak in a mesh?

i plotted a mesh and i am trying to get the exact co-ordinates of the peak.

You should be able to use max() on the z data. How you look up the corresponding x,y values depends on how your data is arranged.

[x,y,z] = peaks(100); % x,y are matrices

[~,idx] = max(z,[],'all','linear');
[m n] = ind2sub(size(z),idx);
peakloc = [x(1,n) y(m,1) z(m,n)]

peakloc = 1×3

-0.0303 1.6061 8.0926

mesh(x,y,z); hold on
plot3(peakloc(1),peakloc(2),peakloc(3),'o')
