How can I sava a series of variables to a txt file?

Hi all,

I have a huge series of variables in the matlab workspace. Below you'll find an example of how one of these variables looks like. The problem comes when I want to save all of them to a single textfile. The code below works, although I know there must be a more elegant and faster way to do is. Note that some variables are missing (data3, data5 and data6).

Can someone please help me?

data1 = [297.08,29.54,80.75];

fid = fopen('alldata.txt','w');
fprintf(fid,'%d\t%d\t%d\n',data1');
fprintf(fid,'%d\t%d\t%d\n',data2');
fprintf(fid,'%d\t%d\t%d\n',data4');
fprintf(fid,'%d\t%d\t%d\n',data7');

Have you considered save() with the -ascii flag ?

Beyond that, see

Many thanks for your repsonse! I hope you can help me getting this further. I tried save() with the ascii flag as you mentioned although I want to be able to do some text formatting. Now I used the code below but I do not get the right values. alldata.txt contains a huge list containing this (=not the data that is in the variables, data1 contains 297.08,29.54,80.75 ):

103.000000  97.000000  117.000000
115.000000  115.000000  105.000000
97.000000  110.000000  115.000000

This is the code I used:

fid = fopen('alldata.txt','w');
  for k=1:300
      try
  textName = ['data', num2str(k)];
  fprintf(fid,'%f\t%f\t%f\n',textName');
      catch
          continue;
      end
  end
