I have an example variable defined as x=[5 1 1 1 1 1 7 1 1 5]; I would like to get the number of ones in each block of consecutive ones, so that my output would look like this: [5 2]. Is there a way to do write a command so that is valid in a loop in which the variable changes both its values and length? Thanks.

x=[5 1 1 1 1 1 7 1 1 5];
start1 = strfind([0,x==1],[0 1]);
end1 = strfind([x==1,0],[1 0]);
end1 - start1 + 1
ans =
5 2
