winplot

Purpose

Windowed plot.

Syntax

    winplot(x)
    winplot(x,w,ws)
    winplot(x,w,ws,flag)
    y=winplot(x,'parm')

Description

winplot(x [,w,ws]) plots means or variances of the sub-vectors of vector x, which have the length w and are shifted by the step ws. x can be a two-column vector, where the first column would be the time-scale.

winplot without any arguments calls a demo (the same as the example below).

Parameters

The optional parameter flag can determine the kind of the result, where flag can be either a string or a scalar:
   'mean' or 1  -  Mean (1st moment).
   'var' or 2  -  Variance (2nd moment).
   'std' or 3  -  Standard deviation.
   'median' or 4  -  Median.
   'sqm' or 5  -  Squared Mean.
   'geo' or 6  -  Geometric Mean.
   '3rd' or 7  -  3rd moment.
   'skw' or 8  -  Skewness.
   'kur' or 9  -  Kurtosis.

Example

    winplot(randn(2000,1),20,20)
