Description

Multi-variate version of ERPDistSakoeChiba_fast. Uses the L1 norm for point-to-point distance computations.

Usage

1
ERPDistSakoeChibaMult_fast(x, y, gapValue, windowSize)

Arguments

x

1st numeric matrix/multi-variate time series.

y

2nd numeric vector/multi-variate time series.

gapValue

If an element of one series is not matched to the other series, its distance to the gapValue is computed instead (0 might be a sensible default for standardized series).

windowSize

The maximum index difference which is considered when matching elements.

Value

The distance as double (not-a-number if matching is not possible as the time series lengths differ more than windowSize).
