Re: Transform list into matrix

[Ivan Reche]

Two million rows may not fit your RAM. If this is the case, I guess that there is no "easy" way to do that as you will have to manage a buffer to this txt file.

Don't know if Octave has something to automate this kind of operation, though.

Hi everybody!

I am new in using Octave. I have been browsing list as to look for a
solution to my problem, related to matrices, but I have not found an example
helping me. My question is if it is possible to construct a matrix from one
net list (like Pajek .NET). This is one example which I have:

A B 5
A F 7
A K 4
A X 8
B D 1
B P 1
B Z 9
C L 6
C O 2
...

The real list have around 2 million of rows and I would have to load from a
TXT file. Is there a easy way to do all this?

Thank you so much in advance.

Best!

AJ
