Generate a 21 times 21 mesh on a xy coordinate system Mesh x

Generate a 21 times 21 mesh on a xy coordinate system. Mesh x & y are bounded in a square -1 lessthanorequalto x lessthanorequalto 1 & -1 lessthanorequalto y lessthanorequalto 1. At each grid point, u(x, y) = 1/x^2, v(x, y) = 1/y^2. Plot (u, v) vector at each grid (x, y) in the given region.

Solution

dx = 0.1 ;

[ x , y ] = meshgrid ( -1.05: dx: 1, -1.05 : dx : 1) ; % creating meshgrid

u = 1./x ;

v = 1./y ;

quiver (x,y,u,v);
