Hello Samuel,
read() never works OK with m = -1, see your own comment in Bug 15075!
This prevented me from upgrading to Scilab 6 until I found out how to do
it with fscanfMat(). But then I had to remove all blank lines in my
files (which I had to quickly find different parts of my data).
--> tic(), M = fscanfMat(myfile); toc()
ans =
0.125278
--> size(M)
ans =
13702. 9.
--> tic(), M = mgetl(myfile); toc()
ans =
0.050891
--> tic(), M = evstr(M); toc()
ans =
1.854611
evstr is slow with large text vectors, compared to file reading.
--> size(evstr(mgetl(myfile, 1)), 2)
ans =
9.
--> tic(), M = read(myfile, -1, 9); toc()
ans =
17.418157
So you have to know the file size completely (and when do you?)!
--> tic(), M = read(myfile", 13702, 9); toc()
ans =
0.085636
Regards
Stefan

Hello Daniel,
In addition to Antoine simple and efficient solution, the following
works as well (and may be a bit faster for big files. To be confirmed):
File = "output.txt";
m = read(File,-1, size(evstr(mgetl(File,1)),2));

Good evening everyone,
I'm integrating scilab with other software, so I need to read an output file
(.txt), like the one attached (output).
It is worth mentioning that this file does not always have the same
dimensions (matrix), so I am trying to find something robust that can deal
with this particularity. I tried to use the 'csvread' function and the
'read' function, but I still haven't been successful ... Any suggestions?
