RIM quantifier of the Weighted OWA function
Description
Function for building the RIM quantifier of the Weighted OWA function
Usage
wowa.weightedOWAQuantifierBuild(p, w, n)
Arguments
p |
The weights of inputs x |
w |
The OWA weightings vector |
n |
The dimension of the vectors p,w |
Value
output |
A structure which has fields: spl, which keeps the spline knots and coefficients for later use in weightedOWAQuantifier, and Tnum, the number of knots in the monotone spline |
