Can any one plz guide how to find the individual intensity of multifocusing spots.Like in the figure below in lumerical we got color bar whose max value corresponds to the max value of the any of the focusing spot out of the existing multiple spots but if we are interested to find the intensity of each focusing spot then what to do .Like the upper spot having peak intensity little bit different thaen that of lower spot how we could evaluate the spots intensity individually?

You can use two matrices to represent the data for the upper and lower peaks, and then create meshgrid like this:

X=meshgridx(x,y);

Y=meshgridy(x,y);

maxe2=max(e2);

indexe2=find(e2(:,:,1,1),maxe2);

?X(indexe2);

?Y(indexe2);

where e2 is the intensity sub matrix.
