Here's some Matlab code:

% Assume 'x' is the input time-domain sequence and 'y' is it's Hilbert transform.

Analytic_Signal = hilbert(x); y = imag(Analytic_Signal);

Instantaneous_Magnitude = abs(Analytic_Signal);

Instantaneous_Phase = unwrap(atan2(y, x));

Instantaneous_Freq = diff(Instantaneous_Phase);
