wsum

wsum

A weighted summation.

Usage:

wsum(xv,yv,w,s,r)

Parameters:

xv

A scalar vector.

yv

A function vector (yi=f(xi)) with the same length as x.

w

The weighting function: a rectangle (0), a triangle (1), a Hanning window (2) or a Hamming window (3).

s

Normalize the results (0|1). If 1 -> scale with "1 / sum-of-weights".

r

The summation extent. r can be one, two or three arguments (see sum for details). Note, however, that the extent is given in values on the x-scale, not in indices.

Result:

A scalar or vector depending on the parameters.
