RE: Loading a matrix from ASCII file (avoiding scripting?)

[Hall, Benjamin]

Things might be working correctly, only your data is stored in a variable
called "xxx", try typing "xxx" (or whos) to see if you have your data.

If you want to change the variable name, try (this will also give you some
visual feedback that the data has been loaded -- note no ";" at the end)

x = load("xxx.txt")

Subject: Loading a matrix from ASCII file (avoiding scripting?)


Hi all !

I am a newcomer to Octave and to this list, so this is my chance to say hi
to everybody ! :-)

----------------------------------------------------------------------

My problem is that I would like to be able to load into arrays and/or
matrixes some plain, tab-delimited real/integers data.

The file format would be something like the following:

0.0 1.0 3.0
1.0  2.5 5.1


I have browsed through both the manuals AND the archive of this list, and
tried the suggestions but I could not find a suitable working solution.

For example, if I issue the command

Load “xxx.txt”

I recieve the following output:

>> load "xxx.txt"
>> x = ans
error: `ans' undefined near line 3 column 5
error: evaluating assignment expression near line 3, column 3

The file “xxx.txt” is in the correct location (I verified it using the “ls”
command).

I am using Octave for Windows, and I downloaded and installed directly the
binaries version for Win (octave-forge-windows), available at
http://sourceforge.net/projects/octave.

It would great to able to load a matrix without scripting, with a single (or
maybe 2) command... :)
----------------------------------------------------------------------------

Can anyone help?

Thanks all !!

Mauro
