.SH NAME
oscillsing - Oscillating Singularity synthesis
.sp
Author: Paulo Goncalves
.sp
Generates oscillating singularities located in the interval \f(CR[\fP0 .. 1\f(CR]\fP
.sp
.sp
.SH Usage
\f(CR[\fPx,Fj,Fs\f(CR]\fP = oscillsing(alpha,beta,sing_pos,N,show) ;
.SH Input parameters
.RS
.TP
o
\fB alpha \fP : Real positive vector \f(CR[\fP1,n_sing\f(CR]\fP or \f(CR[\fPn_sing,1\f(CR]\fP
Holder strenghts of the singularities
.TP
o
\fB beta \fP : Real positive vector \f(CR[\fP1,n_sing\f(CR]\fP or \f(CR[\fPn_sing,1\f(CR]\fP
Chirp exponents of the singularities
.TP
o
\fB sing_pos \fP : Real vector \f(CR[\fP1,n_sing\f(CR]\fP or \f(CR[\fPn_sing,1\f(CR]\fP
Location of the singularities in the interval \f(CR[\fP0 .. 1\f(CR]\fP
.TP
o
\fB N \fP : Integer
Sample size for the synthesized signal
.TP
o
\fB show \fP : flag 0/1
\fI flag \fP = 0 : no display
\fI flag \fP = 1 : displays the instantaneous frequencies and the
synthesized signal
.RE
.SH Output parameters
.RS
.TP
o
\fB x \fP : real vector \f(CR[\fP1,N\f(CR]\fP
Time samples of the synthesized signal
.TP
o
\fB Fj \fP : real matrix \f(CR[\fPN,n_sing\f(CR]\fP
instantaneous frequencies (each column of \fIFj\fP contains the
frequency chirp of each singularity)
.TP
o
\fB Fs \fP : real
sampling frequency
