Adapt the procedure developed in Example 6 to rotate the square counterclockwise by increments of π/10 about the origin. Stop when the square is in its original location and then rotate it in the clockwise direction until the square is in its original location again. You may want to rescale the axis to axis([-2,2,-2,2]) Include the M-file. Do not include the figure.
Hint: Since you are performing a computation several times, you will want to use two for loops: one loop for the counterclockwise rotation and another one for the clockwise rotation. Think about how many times you will need to go through the loops, keeping in mind that you are rotating the square counterclockwise for a full circle by increments of π/10 and then rotating the square clockwise back again.
