Making consecutive 1s and 0s as a seperate element

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

but this is giving last element as '1' instead of '1 1'!

Try the updated code.

Answer 3

[Adam Danz]

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));

celldisp(b)

 
b{1} =
 
     1

 
 
b{2} =
 
     0     0     0

 
 
b{3} =
 
     1     1     1     1

 
 
b{4} =
 
     0

 
 
b{5} =
 
     1
