intcutlincrest

algorithm

returns the integral value of a variable along a single linear cut across the flame front
the flame is defined as a crestline
the cut is determined using the tool lincutcrest
the integral uses the values of variable and the values of the gradient of fdefine along the cut and the matlab tool trapz for the integration
plots the cut and variable along the cut
for batch modus along curvilinear coordinate of crestline use intcutlincrestb

Name	description
X,Y	vectors defining the rectangular domain
XS,YS	coordinates of starting point of the cut
NXS,NYS	components of normal vector defining the direction of the cut
dl	steps between two iterations
varbound	variable defining the boundaries the flame front
variable	variable to be extracted along the cut
CREST	coordinates of crestline defining the flamefront
s	switch (choose level, iso1,iso2 is rel. or absolut) optional input argument, only necessary for iso1 and iso2
iso1, iso2	isolevels defining boundaries of flame front (e.g. 0.9, 0.1) optional input arguments

Name	description
intvar	integralvalue of variable along the cut
plot	cut, variable along cut
