fid = fopen('YourFileNameHere', 'w');
fwrite(fid, YourMatrix, 'float32');
fclose(fid);

Note: you might need to pass transpose(YourMatrix)

I did not research .tim format; the file output format might be more complex than this.

dec2bin is not appropriate for this task.

thanks..but if i use float32..it showing error....below is my code...

   path_02='C:\Users\Desktop\sample';
path_01='C:\Users\Desktop\sample\output';
a = dir(fullfile(path_02, '*.tim'));
for i = 1:numel(a)
  filename_in  = fullfile(path_02, a(i).name);
  fid = fopen(filename_in,'r');
  ascii = fread(fid, [42,21000], 'float32'); 
  data_values=ascii';
  out = fopen(fullfile(path_01, a(i).name),'w');
  fwrite(out, data_values,'float32');
   fclose(out);
  fclose(fid);
end

this is error im getting...

 Error using fwrite
Invalid file identifier.  Use fopen to generate a valid file identifier.

 Error in my_sample (line 14)
  fwrite(out, data_values);

[Walter Roberson]

your fopen() is failing when you want to fwrite(). You should be checking the output file identifier ("out" in your code), and you should consider printing out the reason code

[out, msg] = foen(fullfile(path_01, a(i).name),'w');
if out < 0
   fprintf(2, 'Open to write failed because: %s\n', msg);
else
  ....
end
