please help with the creation of a matlab 2D animation explained bellow

Create an animated plot sequence lasting for approximately 20 to 30 seconds. The animation is expected to include at least some (but not necessarily ALL) of the following elements: ∗ A variety of objects (circles, rectangles, ellipses, spirals, etc.) moving across the plot area ∗ Objects in angular, periodic or more complex (possibly random) motion ∗ Objects changing shape/size/colour, preferably while in motion ∗ Objects appearing/disappearing/transitioning/fading into the background

Since this sounds like an assignment i'll just drop this link.

See the FAQ:

http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F

http://matlab.wikia.com/wiki/FAQ#How_do_I_create_an_ellipse.3F

Also look up rect() or plot() or line() in the help.

Use pause() to adjust the time between objects plotted at different positions.
