Examples
u=prbs_a(50,10); plot2d2("onn",(1:50)',u',1,"151",' ',[0,-1.5,50,1.5]); |  |  |
pseudo random binary sequences generation
[u]=prbs_a(n,nc,[ids])
generation of pseudo random binary sequences
u=[u0,u1,...,u_(n-1)]
u takes values in {-1,1} and changes at most nc times its sign.
ids can be used to fix the date at which u must change its sign
ids is then an integer vector with values in [1:n].
