.SH Usage
\f(CR[\fPy\f(CR]\fP = lambdak(u,k)
.SH Input parameters
.RS
.TP
o
\fBu\fP : real vector \f(CR[\fP1,n\f(CR]\fP
Argument of the function \fIlambdak\fP.
.TP
o
\fBk\fP : real scalar
Parameter of the \fIlambdak\fP function. K=-1 corresponds to the \fIUnterberger \fP distribution; K=0 corresponds to the \fI Bertrand \fP
distribution; K=0.5 corresponds to the \fI D-Flandrin \fP distribution;
K=2 corresponds to the \fI Wigner-Ville \fP distribution on analytic
signals.
