- watex.utils.exmath.betaj(xj, L, W, **kws)[source]#
Weight factor function for convoluting at station/site j.
The function deals with the discrete hanning window based on ideas presented in Torres-Verdin and Bostick, 1992, https://doi.org/10.1190/1.2400625.
- Parameters:
xj – int, position of the point to compute its weight.
W – int, window size, presumes to be the number of dipole.
L – int : length of dipole in meters
kws – dict , additional
scipy.intergate.quad()functions.
- Returns:
Weight value at the position xj, prefix-x`is used to specify the direction. Commonly the survey direction is considered as `x.
- Example:
>>> from watex.exmath import betaj >>> # compute the weight point for window-size = 5 at position j =2 >>> L= 1 ; W=5 >>> betaj (xj = 2 , L=L, W=W ) ... 0.35136534572813144
