Synopsis
average(a,axis=0,weights=None,returned=False)
Returns a’s average along
axis. When axis
is None, returns the average of all
a’s elements. When
weights is not None,
weights must be an array with
a’s shape, or a
one-dimensional array with the length of
a’s given
axis, and average
computes a weighted average. When returned
is true, returns a pair: the first item is the average, the second
item is the sum of weights (the count of values, when
weights is None).
