FFTEngy:
-------------------------------------------------------------------------------
Plot the energy in a signal. Will annotate peaks if y is a 1-dimensional
array. y may be entered by column or row, but the longest dimension
will be assumed to be the variation by time.
-------------------------------------------------------------------------------
Form:
[e, w] = FFTEngy( y, tSamp, aPeak, noLog )
-------------------------------------------------------------------------------
------
Inputs
------
y (:,n) Sequence
tSamp (1,1) Sampling period
aPeak (1,1) Anotate peaks about this fraction of max
noLog (1,1) If input will not use a log plot
-------
Outputs
-------
e Energy
w Frequencies (rad/sec)
