countPaths: Count the number of warping paths consistent with the constraints.
Description
Count how many possible warping paths exist in the alignment problem passed
as an argument. The object passed as an argument is used to look up the
problem parameters such as the used step pattern, windowing, open ends, and
so on. The actual alignment is ignored.
Usage
countPaths(d, debug = FALSE)
Value
The number of paths.
Arguments
d
an object of class dtw
debug
return an intermediate result
Author
Toni Giorgino
Details
Note that the number of paths grows exponentially with problems size. The
result may be approximate when windowing functions are used.
If debug=TRUE, a matrix used for the computation is
returned instead of the final result.
