Matlab command for direction field

I have input the following commands to plot the direction field and it is not working. The domains for t and y is restricted as per the question given. Not sure if 0.02 is correct. Could you please help with commands to plot the direction field.

[t y]=meshgrid(0:0.02:0.1,0.2:0.02:1.4); dy=(cos(y)+3)./y; dt=ones(size(dy)); quiver(t, y, dt, dy);
