Hilbert transform

[Michal Tarana]

Hi everybody,
^^^^^^^^^^^^^

please, could anybody write me the definition of hilbert transform
function hilbert(z) from octave forge package? What is the coefficient
before the integral? Usually it is defined as
H[f(x)](z)=(1/2pi)*int[f(y)/(z-y)]. But in function in octave-forge,
what is instead od 1/2pi?

Thanks in advance.

Michal
