tsstd = std(tsobj) tsstd = std(tsobj, flag)
Financial time series object.
(Optional) Normalization factor:
flag = 1 normalizes by n (number of observations).
flag = 0 normalizes by n-1.
tsstd = std(tsobj) computes the standard deviation of each data series in the financial time series object tsobj and returns the results in tsstd. The tsstd output is a structure with field name(s) identical to the data series name(s).
tsstd = std(tsobj, flag) normalizes the data as indicated by flag.
