I have a table that has a time column and a binary stability column (1 for stable data, 0 for non). I want to create a run count / run log for the stable data as shown below. The idea is to group stable data into "runs" then breakdown the table and export these runs into separate tables or to identify what range in which a run occurs. The table is rather long ~30000 lines, so I figured a for loop would be best but I am having difficulty identifying the conditional criteria. I appreciate any assistance.

Attach the sample data (can make it up, but whole lot easier otherwise... :) )

I think this is what you are looking for:
switch_list=zeros(length(data),1);
switch_list(2:end)=data(2:end,2)-data(1:end-1,2);
up_list=find(switch_list==1);
down_list=find(switch_list==-1)-1;
for i=1:length(up_list)
data(up_list(i):down_list(i),3)=i;
end
I made my own data:
data = [
1 0
2 0
3 0
4 1
5 1
6 0
7 0
8 1
9 0
10 0
11 1
12 1
13 1
14 0
15 0
16 0
17 0
18 1
19 1
20 1
21 0
22 0
23 0
24 1
25 1
26 0
27 1
28 0];

I appreciate all the help. I was able to accomplish what I wanted through a series of if statements within a for loop. Thank you again for your assistance.
