in three different ways
optionally specifying
with these data sequences
Capabilities
≺ apply ≻ is one of { rolling, tiling, running }
keywords (optional)
- padding = nopadding (omit padding) [or use this value]
- atend = false (pad the start) [true, pad the end]
data sequences
- as provided
- ≺ apply ≻(winfn, winwidth, seq)
- with weights
- ≺ apply ≻(winfn, winwidth, seq, weights)
data matrix
as provided
- ≺ apply ≻(winfn, winwidth, data_matrix)
with shared weights
- ≺ apply ≻(winfn, winwidth, data_matrix, weights)
with unique weights
- ≺ apply ≻(winfn, winwidth, datamatrix, weightmatrix)
(each data matrix column is independent – use unary functions)
