Generate one-sided exponential amplitude modulation.
Y = amexpo1s(N) Y = amexpo1s(N,T0) Y = amexpo1s(N,T0,T)
a positive integer value: the number of points.
a positive scalar: the arrival time of the exponential (default : N/2).
a positive scalar: the time spreading (default : 2*sqrt(N)).
a real row vector: the signal.
amexpo1s generates a one-sided exponential amplitude modulation centered on a time T0, and with a spread proportional to T. This modulation is scaled such that Y(T0)=1.
