I'm trying to work my way through the Stanford open machine learning course and it requires me to run a.m file called submit1.m I have this file and i have made sure i am in the correct directory. When i try to run this file and submit my answer example - submit1.m(eye(5,5) I receive this error message: error: `submit1' undefined near line 9 column 1 Sorry in advance if I'm missing something really simple but I am a completely new to octave. I have search for an answer on many forums but none of the given solutions are working for me. If any more information is required please ask and i will do my best.
For the zip archives, the user should extract the file content to a directory on the harddrive (such as C: Octave). Manual shortcuts can then be created to either the octave.bat or octave.vbs files in the main installation directory. Note that starting with Octave 4.4.0, the shortcuts will no longer start the graphical user interface by default. Feb 26, 2010 - Hi, I'm a beginner and am trying to install Octave 3.2.4 on ubuntu. I have a 64 bit processor. I downloaded a.tar.gz file from this website:. Download octave ubuntu, octave ubuntu, octave ubuntu download free.
