Toggles the drawing of grid lines on the currently active plot. The general syntax for its use is
grid(state)
where state
is either
grid('on')
to activate the grid lines, or
grid('off')
to deactivate the grid lines.
Here is a simple plot without grid lines.
--> x = linspace(-1,1); --> y = cos(3*pi*x); --> plot(x,y,'r-');
Next, we activate the grid lines.
--> plot(x,y,'r-'); --> grid on
