loading multiple datafile

[baptiste auguie]

Hello,

A newbie question: I have these datafiles "datafile1.dat",  
"datafile2.dat",... "datafile347.dat", which I want to load and use  
in Octave (e.g, to plot some data as shown below). For one single  
datafile, I would do,

> load     datafile1.dat
>
> x1= datafile1(:,1);y1=  datafile_1(:,3);
>
> __gnuplot_set__  term aqua
> __gnuplot_set__  title "title"
> __gnuplot_set__  xlabel 'Wavelength (nm)'
> __gnuplot_set__  ylabel 'Transmission (a.u.)'
>
> plot(x1,y1./max(y1))


and the result is fine. But I can't figure out a way of dealing with  
many files. Obviously, I can duplicate the lines and change the  
filename, but it's not an option with lots of files. I tried  
something like:

> load *.dat

or

> load [a-b].dat

,...
without any success.

In Matlab, which I'm more familiar with, I'd do something like,

> tab_i=[1: 2]; %filenames numbers of interest
> for i=1:length(tab_i)
> filenames{i}=['data' num2str(i) '.dat']; % string array of filenames
> dataCollect.value{i}=load(filenames{i}); %
> hold on
> plot(dataCollect.value{i})
> end
>
> hold off

(probably a weird way to do it, anyway...)

With Octave's load function, I can't seem to pass a filename I've  
constructed automatically. What would you suggest?

Many thanks,

All the best
