crestline
algorithm
- finds line of peak values of a variable (for example temperature, heat release)
- cuts off values lower than user defined threshold
- searches for three flames
- searches for four branches in each flame
calling the tool branch
- finds and blocks direction of current branch before
searching for a new one calling the tool checkbranch
- cleares values of previous flame before searching for a new one calling the tool rubber
- plots points of crestline
- plots values of crestline along curvilinear coordinate
syntax
[CREST,cc]=crestline(X,Y,t,cut)
example for input
[CREST,cc]=crestline(X,Y,temperature,0.6)
