How do I find consecutive number on (0,1) matrix and for how arrays did I have the number 0 before changing

Hello everyone, I'm trying to solve a unit commitment problem and in order to do that I need to find the number of periods a unit has been offline prior to startup. For example I have a matrix like [0; 1; 1; 0; 0; 0; 0; 1] and I need to calculate when did 0 change to 1(in which array) and for how many arrays did I have the number 0 before changing to 1. Thanks a lot in advance
