How to programm a 2d crosscorrelation

[ntom]

Hello,
I have two intensity plots with the same number of x,y pixels. I would like to know how are they correlated to each other e.g. if the intensity in plot A decreases then what is happening in plot B.
The results should be also a 2D array to produce an intensity graph.
Thanks in advance
PS I use LabView 6.0 for Windows

Since intensity plots are 2D arrays, you should use the array function to compare these plots. You can use comparison functions on the arrays, too.
