RIDGECHAINS Forms ridge curves by connecting transform ridge points. RIDGECHAINS is a low-level function called by RIDGEWALK. [ID,IR,JR,WR]=RIDGECHAINS(N,BOOL,W) forms chains of ridge points of wavelet transform W. Ridge points are all points of W for which BOOL, a matrix of the same size as W, is true. Only ridges with at least N periods are returned. ID is a unique ID number assigned to each ridge. IR and JR are the time- and scale-indices along the ridges. WR is the wavelet transform along the ridge. All output variables are the same size. See also RIDGEWALK. Usage: [id,ii,jj,xr]=ridgechains(N,bool,x); __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2006--2015 J.M.
