Use MATLAB to generated the direction field for following autonomous differential equation.

$\frac{dy}{dx}=y(1-\mathrm{.}25y),$ You can use the script below. Print out the direction field or take a picture with your smart phone. Hand draw the solutions to the differential equation for the following initial conditions:

$y(0)=8$

$y(0)=0\mathrm{.}1$

$y(0)=-0\mathrm{.}1$
