Favorite MATLab Demonstration
My favorite MATLab demo was one where the user takes a normal sine wave and converts it into a series of almost rectangular waves. To do this, the user repeatedly adds harmonics that are smaller than the original sin(t), causing smaller waves to be formed at the max and mins of the original wave. Lastly, colons are used to set k to be every other digit from 1 to 19 in the equation sin(k*t)/k, which allows a function to be created that goes up to the 19th harmonic. The plot of this function looks very close to a square wave, although Gibb's law says that the wave can never truly be square.
