phase and magnitude computation
matrix or row vector of complex numbers.
"continuous" representation between -infinity and +360 degrees (default)
representation between -360 and 0 degrees
phases (in degree) of
magnitude (in Db)
phasemag computes the phases and magnitudes of the entries
of a complex matrix. For
phi(:,i+1) to minimize the distance with
phi(:,i), i.e. it tries to obtain a "continuous
representation" of the phase.
To obtain the phase between -%pi and %pi use
