Multi-variate version of ERPDist_fast
. Uses the L1 norm for
point-to-point distance computations.
1 | ERPDistMult_fast(x, y, gapValue, normalize = FALSE)
|
x |
1st numeric matrix/multi-variate time series. |
y |
2nd numeric matrix/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). |
normalize |
Divide by the length of the longer time series (= minimum amount of assignment steps) to account for series of different lengths in your dataset. |
The distance as double.
