Octave 3.0 - Can't run .m files

[rg_stephens]

I can't get even the simplest program to run in Octave 3.0. Version 2 seemed ok. It runs most of the files I created in school last year in MATLAB, but if I try to write a file it doesnt' run, regardless of the file extension.

For example, I open Kate, or any other editor and type:
% Test file
disp('This is a test')

I save the file as testfile, and this is the result I get when I try to run it:

octave:1> testfile
error: `testfile' undefined near line 1 column 1

% test file
disp('This is a tester File::::!')
A = [3 4 5
6 7 8
9 2 1]


$ octave -q test.m
This is a tester File::::!
A =

3 4 5
6 7 8
9 2 1

Does testfile.m at the prompt work?

Also make sure you are in the directory you saved it in pwd and cd work like normal in octave

Hey, it almost worked that time. Sometimes it works, and sometimes it doesn't. Last night I spent hours and couldn't get anything to run unless I copied and pasted into the octave window.

octave:1> testfile.m
This is a tester File::::!
A =

3 4 5
6 7 8
9 2 1

error: can't perform indexing operations for <unknown type> type

Ok, this time I'm certain that I'm in the correct directory. I type a file using gedit, save it to the 'octave' folder, run 'ls' to make sure it's there, and when I try to run it, ...

% Test file
m = 1
x = m+1;
disp(x)


octave:3> Adding.txt
error: `Adding' undefined near line 3 column 1

Also, the exist command doesn't work. Am I missing something?
octave:5> exist Adding.txt
parse error:

syntax error

>>> exist Adding.txt
^

M-files need to have .m extension... Name your file to Adding.m and it should work.

Might be a problem with the file extension. Octave does not run .M files. Must be .m
I consider this 'system feature' an (annoying) bug. (My DOS based data acquisition system unavoidably generates .M files).
People from the W#%dows environment will have more difficulty with getting used to this this. Linux is case sensitive, also in the file extension.
