__getitem__ ( self,  idx )

Slide access to the analog record indices

__init__ (
        self,
        ANALOGobj,
        patterns,
        smoothing=1,
        weightexp=2.0,
        report="",
        )

Constructor for the ANALOGSelector class

Arguments:

ANALOGobj

An instance of an analog class (EOFANALOG or CCAANALOG)

patterns

Base patterns (along the first axis) for which the analogs are searched

Optional arguments:

smoothing

The number of analogs to average. Defaults to 1 (i.e. single analog search)

weightexp

In the weighted averages sets the power to raise the inverse euclidean distance in the weights. Defaults to 2 (inverse squared distance weights).

report

Filename where to dump a detailed report of the search. The default behavior is not to dump any report.

returnAnalogs ( self,  field=None )

Returns the single analog (smoothing=1) reconstructed field

The output is exactly the same as that of the method returnAverage() It's just a notation matter. There is no need to use this specific method for the case smoothing=1 if you are, for instante, into a loop over several smoothing factors.

Optional argument:

field

To reconstruct the analogs in a field different from the library dataset. The first axis dimension must match that of the library dataset.

returnAverage ( self,  field=None )

Returns the average reconstructed field

Optional argument:

field

To reconstruct the analogs in a field different from the library dataset. The first axis dimension must match that of the library dataset.

returnWeightedAverage ( self,  field=None )

Returns the weighted average reconstructed field

Optional argument:

field

To reconstruct the analogs in a field different from the library dataset. The first axis dimension must match that of the library dataset.
