MATLAB: Is there a function in MATLAB 7.0 (R14) that will allow me to read a text data file with multiple header rows interspersed with data

Question

I have a text file that is set up as follows

 H1 H2 H3 H4
 1 2 3 4
 5 6 7 8
 H5 H6 H7 H8
 9 10 11 12
 13 14 15 16
 17 18 19 20

My objective is to import all the numeric data discarding any rows containing text headers.

Answer 1

The following code snippet illustrates how this can be achieved

fid = fopen('mydata.txt', 'r');
d = {};
while ~feof(fid)
      fgetl(fid); % header row
      c = textscan(fid, '%d %d %d %d'); %Four data columns.
      d = vertcat(d, c); 
     %Alternatively, d = [d; c]
end;
fclose(fid);
