How can I combine data from multiple cells into one matrix?

I have a cell that contains 233 matrices, each with data in it. I would like to pull all of this data into one matrix with 23 columns, however I run into problems because each matrix does not have the same number of rows, though they all have 23 columns. This code pulls most of the data into the matrix, but still overwrites some lines when multiple columns are being added from the same matrix.

load('initialdata.mat'); %1x233 cell

k=length(initial data);

for i=1:k

   finaldata = zeros(23,500); %500 is arbitrary 

      m=1
      z=0

      for j = 1:500
          j = m
         [row column] = find(timecell{1,j});
          if length(row) == 23
              z= 1
              for i = 1:23
                  finaldata(i,j) = (timecell{1,j}(1,i));
              end
          elseif length(row) > 23
              for z = 1:length(row)/23
                  for i = 1:23
                      finaldata(i,j+z) = (timecell{1,j}(z,i));
                  end
              end
          elseif length(row) == 0;
              z= 0
          end
          m = j+z
     end
 end

Thank you!

A={rand(4,23) rand(5,23) rand(10,23)}
B=cell2mat(A')

This worked perfectly. Thank you!

What is your cell array called? "initial data" is not a valid variable name so don't know how that got past the length() call. Is it timecell? Did you try something like

finaldata = timecell{:};

If that doesn't work, maybe try transposing timecell. Otherwise go down cell by cell concatenating with a semicolon

for k = 1 : length(timecell)
    if k == 1
        finaldata = timecell{k};
    else
        finaldata = [finaldata; timecell{k}];
    end
end

Oops, yes it is timecell, not initial data. Transposing worked, thank you!
