what is the error here?

data1 = [data1,(text(k,6))];

Error using horzcat CAT arguments dimensions are not consistent.

Error in data1 = [data1,(text(k,6))];

[Amr Hashem]

 for Q=1:length(querymdr)
    for k=1:length(text)
       if  datatext{Q,1}==text{k,1}
           M=text(k,6);
         data1 = [data1,(text(k,6))];
          k=k+1;
           end
    end
end

[James Tursa]

What are the contents of datatext and text? I.e., what are the underlying variable types and sizes?

Are you sure you want the test to be datatext{Q,1}==text{k,1} and not something like isequal(datatext{Q,1},text{k,1})?

Why are you manually incrementing the for-loop index k within the loop?

[Amr Hashem]

this is the contets of datatext and text

datatext 5*6 cell text 8*6 cell

i want the answer to be:

ans 5*8 cell

[Amr Hashem]

any help, this is the code

    for Q=1:length(querymdr)
        for k=1:length(text)
           if  datatext{Q,1}==text{k,1}
             datatext = [datatext,(text(k,6))];
           end
        end
    end

You need to find an empty position in datatext(Q,:) to assign into. For example,

nextslot = find(cellfun(@isempty,datatext(Q,:)));
if isempty(nextslot)
  nextslot = size(datatext,2);
end
datatext{Q,nextslot} = text{k,6};

This will grow datatext wider if necessary in order to handle the new information.
