Hello,
I am trying to determine the beginning and end points of a pulse like the plot below. I have seven of these pulses saved in an array called Pulse_arry(1, 7) and would like to be able to find the beginnign and end points for each individually. Would anyone know a simple way to do this? I do not have access to functions like dutycycle or pulseperiod so it would have to be done a different way.
Thanks for any help

Either first negate the pulse (multiply it by -1) and then use findpeaks, or use islocalmin (possibly with find) to determine the beginning and end.
