MATLAB: Import Text File Data With Blank Rows

import blank rowimportdata

I am having trouble importing a data set from a text file with blank rows. The data is in file "set1.txt" (attached) formatted as follows:
X data    Y data
-----------------
   1       5
   2       7.8
   3       2.1
X data2   Y data2
-----------------
   1       2
   2       2.4
   3       8
When I use
G=importdata('set1.txt');
I have the first set of data contained in
>>G.data
ans= 
   1       5
   2       7.8
   3       2.1
Everything below the blank (empty) row is ignored. What I'd ultimately like to do is import each chunk of data into either its own n x 2 matrix, or, into an appended matrix such that all the data in set1.txt is imported into a matrix with the following format:
     1       5       1   2
     2       7.8     2   2.4
     3       2.1     3   8
Any help would be much appreciated!

Run the following
 content = fileread( 's1.txt' ) ;
 blocks  = regexp( content, '-[\n\r]+([^X]*)', 'tokens' ) ;
 blocks  = [blocks{:}] ;
and look at the content of blocks{1} and blocks{2}. Then see Per's answer in the thread that he links above. You can proceed the same way; I just wanted to provide you with a pattern which matches your setup, as it can be tricky to build if you are not familiar regular expressions.
