Re: [Scilab-users] Put .txt data in matrix
I use to read text files with Scilab. This piece of code is close to the one I use. To save time, one can give a dimension to ‘m’ : Instead of m=[] Prefer m=zeros(1,4); // by-exemple Gilles Tel : +33 (0)4 42 25 20 33 - Mob : +33 (0) 6 87 99 19 57 - Fax : +33 (0)4 42 25 49 17 gilles.gobil...@cea.frmailto:gilles.gobil...@cea.fr De : users [mailto:users-boun...@lists.scilab.org] De la part de simon_37 Envoyé : jeudi 12 décembre 2013 10:46 À : users@lists.scilab.org Objet : Re: [Scilab-users] Put .txt data in matrix Hi Osvaldo, Thanks for your reply.

Re: [Scilab-users] Put .txt data in matrix
Thanks you to everyone for their help.
It's finally done.
I drop my code :
[FileName,PathName] = uigetfile('','','sélectionnez le(s) fichier(s) à
traiter',%t);
f = fullfile(PathName, FileName)
f1 = mopen(f,r);
garbage = mgetl(f1,15);
m = [];
while ~meof(f1)
line = mgetl(f1,1) // read one line
if line == [] then
break
end
lineNr = eval(tokens(line))' // dont forget the '
m = [m;lineNr] // add one line to m
end
x1=m(:,1)
y1=m(:,2)
x2=m(:,3)
y2=m(:,4)
plot(x1,y1)
Regards
Simon

Hi Osvaldo,
Thanks for your reply.I think your "piece" of code is the most efficient that I search.
But Scilab don't recognize the "not" in the while loop parameters...
I am trap.RegardsSimon

If you want to ignore exactly the first 15 lines, you can use:f = mopen("your file","r");
garbage = mgetl(f,15);m = [];while not meof(f)ÂÂÂ line = mgetl(f,1); // read one line
ÂÂÂ lineNr = eval(tokens(line))'; // dont forget the '
ÂÂÂ m = [m;lineNr]; // add one line to mend

Hello, De : simon_37 [...fscanfMat...] It doesn't work to, I already try it. It return me error 999 I tried it from the data you gave (copy/paste to a .txt file) and it worked. I don't know what error 999 is, it is not in the table http://help.scilab.org/docs/5.4.1/en_US/error_table.html Maybe you could send the text file atached so we can see what happens.
