RIDGEMAP Maps ridge quantities back onto the time series. X=RIDGEMAP(N,XR,IR) where IR is a ridge index and XR is a quantity along the ridge, maps the values of XR to their correct row locations in a time series of length N, and returns the result in the array X. If IR and XR contain L different ridges separated by NaNs, as output by RIDGEWALK, then X is N x L with the values of XR from each ridge in a separate column. Values not specified by the IR are left as INFs. [X1,X2,...,XM]=RIDGEMAP(N,X1R,X2R,...,XPR,IR) also works for any P different ridge quantities X1R--XPR. When using RIDGEWALK's joint ridges algorithm, in which some quantities have more than one column, they should be passed to RIDGEMAP individually, for example [X1,X2]=RIDGEMAP(N,X(:,1),X(:,2),IR). __________________________________________________________________ Collapsing X=RIDGEMAP(...'collapse') combines values from all the ridges using a power-weighted mean. Then X is a column vector of size N x 1. __________________________________________________________________ Ridge multiplicity [...,MULT]=RIDGEMAP returns the ridge multiplicity MULT after all the expected output quantities. MULT is a column vector with size N x 1. The ridge multiplicity is the number of ridges present at each time. __________________________________________________________________ See also RIDGEWALK. Usage: x=ridgemap(N,xr,ir); [x,f]=ridgemap(N,xr,fr,ir); [x,f]=ridgemap(N,xr,fr,ir,'collapse'); [x,mult]=ridgemap(N,xr,ir); [x,f,mult]=ridgemap(N,xr,fr,ir); __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2009--2016 J.M.
