Calculates entropy for data (probability of events) in an array.
In information theory, entropy is a measure of the uncertainty associated
with a random variable. In this context, the term usually refers to the
Shannon entropy, which quantifies the expected value of the information
% contained in a message, usually in units such as bits. In this context, a
'message' means a specific realization of the random...
The program does interpolation or decimation on a given 1-d data in an array.
Given X with sampling rate Ft Hz and is used to generate another sequence Y with sampling rate Ft' Hz, then Sampling Rate ratio R is given by,
Ft'

1-D Covolution
In mathematics and, in particular, functional analysis,convolution is a mathematical operation on two functions f and g, producing a third function
that is typically viewed as a modified version of one of the original...
Implementation of Moving Average filter.
The moving average filter operates by averaging a number of points from the
input signal to produce each point in the output signal. In equation form,
this is written:
1 M-1
