Howcan i get the date of pulse_transition

Hello, I'm Emmanuel student in electronic at the university of Toulouse (FRANCE)

I've got a signal into a vector, il look like a pulse signal and i want to have the date of each rising edge and falling edge into two vectors

mi code is here

pm = dsp.PulseMetrics('TimeInputPort',true,'TransitionOutputPort',true,'PostshootOutputPort',true,...,

'CycleOutputPort', true,'SettlingOutputPort',true,...

'StateLevels',[seuil_bas seuil_haut])

%conversion en ms%

echelle_temps=t*periode_echantillonnage

xlabel('Samples');

pulse,cycle,transition,settling] = pm(s',t');

plot(pm);

I want to specify the rising level and the falling level. Pleased tell if the field settling in dsp.Pulsemetrics is the best way to do that, or are they others ways?

Thanks a lot for your answer

Emmanuel
