MATLAB: I am trying to create a surface plot with nested loops and am getting the error “Z must be a matrix, not a scalar or vector.”

n=1;
for ii = 1:10;
    for jj = 1:10;
        x(n) = ii;
        y(n) = jj;
        z(n) = ii+jj;
        n = n+1;
    end
end
surf(x,y,z)

Best Answer

Try something like the following (z must be a matrix):
for m = 1:10
        x(m) = m;
    for n = 1:10
        y(n) = n;
        z(m,n) = n+m;
    end
end
surf(x,y,z)
