Hello, can someone please show me, how to plot this inequality?
metr(x, point) < radius;
where 'x' is general point in 2D xor 3D, 'point' is concrete point in 2D xor 3D, expression 'metr(x, point) < radius' represents a neighbourhood of the 'point' with radius 'radius'. I would like to plot this neighbourhood to the graph - both in 2D and 3D. Thanks for your help!

Here's an example of plotting an inequality. You'll need to adapt it.
>> v = -5:0.1:5;
[x,y] = meshgrid(v); % create a grid
ineq = x + y >= 1; % some inequality
f = double(ineq);
surf(x,y,f);
view(0,90) % rotate surface plot to top view
