cover cell array into vector

hi all, I have this cell array and I want to conver it into a vector. The problem is that cell2mat will remove the empty cells and I want to keep them as = ' '.

Then I need to build again the cell array from the resulted vectore.

Any help would be appreciated.

You can't store empty '' or [] in numerical array. The best you can do is to replace it with zero or nan

Numeric arrays do not have empty elements: every element has one value.

But you can easily store the sizes and recreate the cell array:

>> C = {[0;0],[],[],[0,1,2,3;0,0,0,0]};
>> S = cellfun('size',C,2);
>> M = cell2mat(C);

Recreate (strictly speaking the empty matrices have different sizes compared to those in C):

>> D = mat2cell(M,2,S);

This works. Thx a lot!
