I have a 3-d matrix z with variables x, y and s. I want to store the maximum value of z over s in a new matrix with variables x and y only. How should I do it?
if true
% code
end
x = 1:32;
y = 1:32;
s = 1:20;
[X,Y,S]= ndgrid(x,y,s);
z= X.^2 + Y.^2 -2.*X.*S +Y.*S;
%Now how do I store maximum of z in a new matrix called zmax(x,y)%

zmax = min(z, [], 3);
