在 MATLAB Online 中打开

a=[0 0 1 1 1 1 0 0 0 0 1 1 0 0 0 0 1 0 1 0 0]
a = 1×21
     0     0     1     1     1     1     0     0     0     0     1     1     0     0     0     0     1     0     1     0     0
starts = strfind([1 a], [1 0])
starts = 1×5
     1     7    13    18    20
stops = strfind([a 1], [0 1])+1
stops = 1×5
     3    11    17    19    22
stops - starts
ans = 1×5
     2     4     4     1     2
