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]

When you create vector in matlab, two elements of vector are separated by comma (,) or space. Meaning of both are same.

I understand what you are stating but my aim is to make consecutive 1s and 0s as seperate elements in an array

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

a = [1 0 0 0 1 1 1 1 0 1];
consecGroups = findgroups(cumsum([true, diff(a)~=0]));
b = arrayfun(@(g){a(consecGroups==g)},1:max(consecGroups));
% Show results
celldisp(b)
b{1} = 1 b{2} = 0 0 0 b{3} = 1 1 1 1 b{4} = 0 b{5} = 1
