NAME
lambdak - k's lambda functions for pseudoAW
Author: Paulo Goncalves
Computes the parametrizing function lambdak defining the Affine Wigner dis-
tributions.
Usage
[y] = lambdak(u,k)
Input parameters
o u : real vector [1,n] Argument of the function lambdak.
o k : real scalar Parameter of the lambdak function. K=-1 corresponds
to the Unterberger distribution; K=0 corresponds to the Bertrand
distribution; K=0.5 corresponds to the D-Flandrin distribution;
K=2 corresponds to the Wigner-Ville distribution on analytic sig-
nals.
Output parameters
o y : real vector [1,n] Result of the function lambdak .
