NAME

Energy - Calculate energy in running windows


SYNOPSIS

    Energy <in.h lwind=21 j1=11 normalize=no average=yes verbose=no > out.h


INPUT PARAMETERS

lwind - integer
      [21]:  number of points in smoothing window
j1 - integer
      [11]:  increment between window centers; 
      equal to subsampling factor; j1=1 is no subsampling.
normalize-char*
      [no]:  convert all energy values to range 
      of 0.0 to 1.0 .  (normalizes each panel separately)
average - char*
      [yes]:  normalizes energy by length of window
verbose - char*
      [no]: gets more loquacious if =yes
n1,n2,n3- int
      standard seplib pars
o1,d1 - real
      standard seplib pars


DESCRIPTION

Calculate energy in running windows along fast axis of data


EXAMPLE

    Energy < in.H lwind=21 j1=11 normalize=no average=yes verbose=no > out.h
        Calculates the trace energy in running windowis with 11-sample distance
        between window centers. The smoothing window is 21 samples long. Normalize
        energy by window length. No cross-window normalization is applied.
