reading multiple file

[nuncio murukesh]

Hi all,
        I am new to octave and started learning it to interpolate some
ocean profile data using spline.  The problem is that I have quite a
number of files, say, 10000 all of which needed to be opened and
interpolate.  If I have file names like file_1.txt,
file_2.txt......file_n.txt, can all the files be opened using the for
loop something like this 
 for i=1,10000
        filename="file_"+i+".txt"
        endfor
        I took this idea from IDL
anyother means would also be greatly appreciated

Thanks
