Count number of cells separating two trues in logical vector

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
