Class _OneDimensionalHitParade

Class to produce hit-parades (i.e., a list of the largest and smallest values) out of a one-dimensional time-series.

Instance Methods

__init__(self, n, d, real_dtype='d', integer_dtype='l')
Input arguments: n -- Number of maxima and minima to remember d -- Minimum gap between two hits

get_maxima(self)
Return the tuple (maxima, time-indices). Maxima are sorted in descending order.

get_minima(self)
Return the tuple (minima, time-indices). Minima are sorted in ascending order.

update(self, inp)
Input arguments: inp -- tuple (time-series, time-indices)

init(self, n, d, real_dtype=`'d'`, integer_dtype=`'l'`)
(Constructor)

Input arguments: n -- Number of maxima and minima to remember d -- Minimum gap between two hits

real_dtype -- dtype of sequence items integer_dtype -- dtype of sequence indices Note: be careful with dtypes!
