<p>Hello,<br>
<br>
Did you try the fscanfMat function to read the file? The following two lines seems to do the job, if I really got the question:<br>
<br>
<font face="Courier New">f = xgetfile() // locate the file</font><br>
<font face="Courier New">m = fscanfMat(f) // read the file over matrix m</font><br>
<br>
You get<br>
<br>
<font face="Courier New"> m =</font><br>
<font face="Courier New"> </font><br>
<font face="Courier New"> 274. 1. 0.2898 </font><br>
