##### Count the number of possible warping paths

Count the number of warping paths compatible with the constraints.

Keywords
ts
##### Usage
countPaths(d,debug=FALSE)
##### Arguments
d
an object of class dtw
debug
return an intermediate result
##### Details

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.

Note that the number of paths grows exponentially with problems size. The result may be approximate when windowing functions are used.

If debug is TRUE, a matrix used for the computation is returned instead of the final result.

##### Value

The number of paths.

• countPaths
##### Examples
  ds<-dtw(1:7+2,1:8,keep=TRUE,step=asymmetric);
countPaths(ds)
## Result: 126
