-y = decimate(x,q) reduces the sample rate of x, the input signal, by a factor of q.
-By default, an order n Chebyshev type I filter is used. If n is not specified, the default is 8.
-If the optional argument "fir" is given, an order n FIR filter is used, with a default order of 30 if n is not given.
-Note that q must be an integer for this rate change method.
