function bolling

[Doug Stewart]

i'm using this function
Function File: bolling (asset, samples)
Function File: bolling (asset, samples, alpha)
Function File: bolling (asset, samples, alpha, width)
Function File: [movavg, upperband, lowerband] = bolling (asset, samples,
...)
If no output is requested, plot the bollinger bands of the asset. If output
is requested, return the values for the bollinger bands. If given, alpha is
the weighting power of the moving average; 0 (default) is the simple moving
average, see movavg for the full definition. width is the number of
standard
deviations to plot above and below the moving average (default: 2).
i read this but i don't understand what is ASSET and SAMPLE..(in the
documentation i don't see it)
'Asset' is a array? and 'samples' is period?
i set Asset with matrix but it don't correct...it need array(n) and not
matrix(n,m)
