add m-files to octave

[Cerny]

I need to download some m-files for my linear algebra class and i can't figure out where to place the files in order for octave to find them. If anyone knows where they would be placed that would be great.

I believe you can add the directory in which the m-files are located to the search path that octave uses using the addpath command as shown below:


octave:2> addpath("/home/dedmonds/octave/mfiles/");


This will not survive through a shutdown of the program, so you would have to do this each time you start octave.

I believe you can also run the path command to see the directories currently in the octave search path. You can place your m-files in one of these directories and, octave should find them.


octave:3> path

Octave's search path contains the following directories:

.
/home/dedmonds/octave/mfiles
/usr/local/share/octave/site-m
/usr/lib/octave/3.0.0/oct/i486-pc-linux-gnu

you can put whereever you want ! just do in an octave session

addpath(genpath("/path_where_you_want/";
savepath;

and all the where_you_want including subdirs behind are included
and even saved for subsequent sessions
