- How to change directory under Octave? For example, the script "myprogram.m" file is saved under
"C:\Documents and Settings\myusername\My Documents\myprogram.m", you need to change the current working directory
under Octave in order to run the script. Type
Then you can type the filename in Octave to run the script:
chdir('C:\Documents and Settings\myusername\My Documents')

For Linux and Mac users, the commend is similar. You only need to type the correct path to the directory in the command 'chdir'.myprogram
