For Loop maximum graph

given a matrix C, i am to find the values of x and y where the plot of C is at max. whenever i run a code that uses the find function, i am returned with the row and column of the element in the matrix instead, and not the x and y points of the graph. any idea how to fix this?

Idk why membrane doesn't allow for the x,y data to be an output argument, but it doesn't. You can just create them anyway.

m = 15; % this is the default
xy = linspace(-1,1,2*m+1);
C = membrane(1,m);

[mxz, idx] = max(C(:));
[r, c] = find(C == mxz);
maxpoints = [xy(c) xy(r) mxz] % [x y z]

maxpoints = 1×3

0.3333 -0.3333 1.0000

surf(xy,xy,C); hold on;
plot3(maxpoints(1),maxpoints(2),maxpoints(3),'ko','markersize',15)
