Method Detail

distance

double distance(double[] a,
                double[] tA,
                double[] b,
                double[] tB)

Calculates the distance between two time series.

Parameters:

a - First time series.

tA - Timestamps for the first time series.

b - Second time series.

tB - Timestamps for the second times series.

Returns:

Distance between the first and second time series.
