How can I get all possible coordinate (x,y,z) from this function function
cos(x) + cos(y) + cos(z) = 0
I've tried this but, it did work.
syms X Y Z z
counter = 1;
for x = -5:5
for y = -5:5
Data.X(counter) = x;
Data.Y(counter) = y;
Data.Z(counter) = solve(cos(x) + cos(y) + cos(z) == 0,z);
counter = counter + 1 ;
end
end

zz = acos(-(cos(-5:5)+cos((-5:5).')))
% Check
norm(cos(-5:5) + cos((-5:5).') + cos(zz))
