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?

Ran in:
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); holdon;
plot3(maxpoints(1),maxpoints(2),maxpoints(3),'ko','markersize',15)
