creating a character array in which each element takes multiple characters put together

I want to assign each element of an n by m matrix with a specefic code that depends on the code of other elements in the matrix

For example in the below picture I want to give the element mm(6,2) a code '0' and element mm(6,1) code'1'

the problem comes here,I want the code of the element mm(5,1) per say to be the code of mm(6,2) with an extra '1' next to its right so it becomes '01'

this is the code I have and I keep running into size problems:

x=size(mm);
xx=x(1)-1;
emptyCell = cell(7,7);
emptyCell(xx,2)={'0'};
emptyCell(xx,1)={'1'};
for i=xx-1:-1:2
    temp=find((mm(i,:)==mm(i-1,2)+mm(i-1,1)));
    emptyCell(i-1,2)={emptyCell(i,temp) '0'}; % here is the error
    emptyCell(i-1,2)={emptyCell(i,temp) '1'}; % and here
end

I want to fill the code that I assigned in emptyCell ,for example I want the blue marked cell to contain '1011',How can I approach this problem?

any help would be appreciated

@Hashem Rawashdeh Why did you edit away your question? That is very rude.

[per isakson]

The RHS of the two assignments in the for-loop are they correct?

Don't show data as images. Seven lines can be included as code.

In this case, I think it's better to use a string array than a cell array of characters (emptyCell). The code becomes easier to read and understand.

I don't fully understand your algorithm.

Below is a code that doesn't throw errors. In the two latter iterations temp is empty. ( == and floating point numbers is not a good combination.) For some reason {horzcat(emptyCell{i,temp},'0')} doesn't throw errors in that case. I believe that {horzcat(emptyCell{i,temp},'0')} does what you intended.
