Hi,
im new to matlab, and ive been trying to learn it on my own, using the help section.. i was trying to do this, it looks very easy, but im not sure how to write to matlab to do this..

I have thousands of signal pulses. And i want to compare their rise times. The rise times are from 0.1Maxpulse height to 0.9xMaxpulseheight.
i need to tell matlab to tell me the rise time. This time is basically this-->(x(a)0.9Maxpulseheight- x(a)0.1Maxpulseheight).... i tried to do this many ways, but have no idea how to tell matlab to do this simple calculation for all my pulses.
