reading file

[marco cammarata]

Hi,

I would like to read a file that looks like this

a b c
1 2 3
4 5 6

in a structure where data.a contains the first columns (e.g. 1 and 4 in
2 rows), data.b the second and so on.

I wrote something that seems to work:
file = "file_to_read.txt";
F=fopen(file,"r");
titles=fgetl(F);
titles=regexprep(titles,'\s+',' ');
titles=split(titles," ");
fields=cellstr(fields);
nfile=0;
while ( (line=fgetl(F)) != -1 )
 if (line == -1)
        break
 endif
 nfile = nfile+1;
 temp=regexprep(line,'\s+',' ');
 temp=split(temp," ");
 temp=cellstr(temp);
 for i=1:size(fields)
        cmd=sprintf("data(%d).%s=\"%s\";",nfile,fields(i),temp(i));
%       disp(cmd)
        eval(cmd);
 endfor
endwhile
close(F);

but it's a bit too slow ... for a 19 columns and 130 rows it takes
almost 2 seconds !!! (on a xeon machine).

Any suggestion ?
Another question,
How can I plot let's say "data.a" ?
Octave complains saying that has noting to plot ...

Many thanks in advance,
attached please find the octave script and a sample file ..
