covar_a

covar_a(fs1, fs2[, area])

Computes the covariance of fs1 and fs2 over a weighted area.

Parameters

• fs1 (Fieldset) – first input fieldset

• fs2 (Fieldset) – second input fieldset

• area (list) – area as [N,W,S,E] to perform the computations

Return type

number or list

If the area is not specified the whole field will be used in the calculation. The result is a number for a single field or a list for a multi-field Fieldset.
