Signal with arbitrary frequency modulation.
[Y,IFLAW]=fmodany(IFLAW) [Y,IFLAW]=fmodany(IFLAW,T0)
vector of the instantaneous frequency law samples.
time reference (default: 1).
output signal
fmodany generates a frequency modulated signal whose instantaneous frequency law is approximately given by the vector IFLAW (the integral is approximated by CUMSUM). The phase of this modulation is such that y(t0)=1.
