Re: Variable Names

[Judd Storrs]

Without knowing the details of the file types or the numbering scheme it's hard to say. If the filenames are sequentially numbered you could do something like this.

First, if the files aren't some standard file handled by octave or the io or
misc packages, the first step I recommend writing a function that takes a file name
and returns the data from that one file. Let's call that load_my_data(). Then

data = "" ;

would read the file into data. 

Now, to load many of them one approach is to generate filenames using sprintf and store the data in a cell array. Suppose you have 500 files named like "Res2006001" to "Res2006501". Something like this should get you started:

for i=1:500
    name = sprintf("Res2006%03d", i) ;
    data{i} = load_my_data(name) ;
endfor

One thing to be careful of is to make sure that you store data into the cell starting at 1.

If it's difficult to generate the filenames, another option is to store the filenames into a cell array and the load the data using names from the cell array:

filenames = {"Res2006001","Res2006002", ................. , "Res2006501"};
for i=1:length(filenames)
    data{i} = load_my_data(filenames{i}) ;
endfor

Hello all,

I'm trying to write a program I can use to load a large number of data files
into Octave. The files all have the same naming convention:

Res2006001
  ...
Res2006365

Does anyone know if this can be done with an M-file? If so, could you give
me some pointers. Thanks,

Joseph
