Their use in conjunction can sometimes be revealing in its own right. Let's look at an example. 1 's upper 4 panels. The 2 patterns generating A and B , and their time behavior. The left panels are for field A , the right panels for B .
Uppermost panels are the first pattern, whose timeseries are shown in red in lower panels.
The middle panels are the 2nd pattern, whose timeseries is given in blue in the lowest panels. Now we want to use SVD analysis to retrieve the operation of the method. The 2 three-dimensional datasets are first turned into matrices. The 3 leading patterns of the cross-correlation matrix of fields A and B . There are a number of things to notice.
