## Compute a dissimilarity matrix, akin to "dist", analogue/distance,
## vegan/vegdist, etc. , based on the dtw "distance" measure.


## Apply FUN to all row pairs
dtwDist <- function(mx,my=mx,...) {
  mye<-function(y,x,FUN,...) {
    apply(x,1,FUN,y,...);
  }

  apply(my,1,mye,mx,dtwpairdist,...);
}
