Count number of cells separating two trues in logical vector

2 views (last 30 days)
Hello!
I would like to find a fast procedure to count the number of cells separating two trues in a logical vector, and store the results in a new numeric vector.
For instance:
x=[true;false;false;false;true;false;false;true;false;true];
The output should be
output=[4;3;2]; % Hence, it counts also the "first" true
Hope the question is clear.
Thank you!

x=[true;false;false;false;true;false;false;true;false;true];
diff(find(x))
ans = 3×1
4 3 2
