kappanew
algorithm
- calculates curvature values in a 2d field in mathematical sence
- calculates curvature of a curve given in implicit form (Bronstein formula(4.25)
- note: kappa calculates values of a matrix;
- use extract after calculation, to extract curvature along flame front
syntax
[k]=kappanew(X,Y,fdefine)
example for input
[k]=kappanew(X,Y,Z) [xiso,yiso,siso,variso,fp3]=extract(X,Y,Z,0.5,k,'abs','no')
