MATLAB: Making consecutive 1s and 0s as a seperate element

Question

If I have a cell say a= [1 0 0 0 1 1 1 1 0 1] I want b= [ 1,0 0 0, 1 1 1 1,0,1]

Answer 1

You can create a cell array

a = [1 1 0 0 0 1 1 1 1 0 1 1];
idx = [1 find(diff(a)~=0)+1 numel(a)+1];
C = cell(numel(idx)-1, 1);
for i = 1:numel(C)
    C{i} = a(idx(i):idx(i+1)-1);
end

Result

>> C{1}
ans =
     1     1
>> C{2}
ans =
     0     0     0
>> C{3}
ans =
     1     1     1     1
>> C{4}
ans =
     0
>> C{5}
ans =
     1     1
