How can i load a multiple 1D matlab file and store in single mat file?

I have around 400 1D mat files of different size. For example data1 having a size of 1X65000, data2 having size of 1X 45900 and so on... upto data400 having a size of 1X 36000.

how can i store this mat file as Result.mat having file size (400 X minimum length)

all_data = zeros(400,0);
for K = 1 : 400
    thisfile = sprintf('data%d.mat');
    filestruct = load(thisfile);
    varnames = fieldnames(filestruct);
    firstvarname = varnames{1};
    this_data = reshape(filestruct.(firstvarname), 1, []);
    if K == 1
      all_data = data;
      Lall = length(data);
    else
      L = length(this_data);
      if L < Lall
          Lall = L;
          all_data = all_data(:,1:Lall);
      end
      all_data(K, :) = this_data(1:Lall);
    end
end

Everything will be in a cell aray but this will do the trick:

for ii = 1:numel(dir('*.mat'))
    result{ii} = load(strcat('data',num2str(ii),'.mat'));
end
