Multi-variate version of ERPDistSakoeChiba_fast. Uses the L1 norm for point-to-point distance computations.
1 | ERPDistSakoeChibaMult_fast(x, y, gapValue, windowSize)
|
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. |
The distance as double (not-a-number if matching is not possible
as the time series lengths differ more than windowSize
).
