Calculating time duration of a signal

I would like to calculate the time duration of a signal. In the example below, I want to write in a 2 column matrix the signal and the duration for the purposes for plotting a histogram.

signal=[0 0 0 1 1 1 1 0 1 1];

Output I'd like to see:

signal duration(ns)

0 3

1 4

0 1

1 2

This is my code so far, I'm stuck at trying to calculate the actual duration. I dont know how to calculate time in between when 0 transitions to 1 and vice versa.

duration=[];

signal=[0 0 0 1 1 1 1 0 1 1];

for c=1:length(signal)

diff=signal(c+1)-signal(c);

if diff~=0

????

end

end

Hello,

You also could refer this code to get the output

clear
signal=[0 0 0 1 1 1 1 0 1 1];
n = length(signal);
a = diff(signal);
b = find(a);
output = [signal(b) signal(end); diff([0 b n])]'

Hi,

Your code definitely worked on a large data file as well.

Thanks very much!
