hi guys,
im noob in octave. i get the following error whenever i load a . m file :

" error: load: test_plot.m: inconsistent number of columns near line 3
error: load: unable to extract matrix size from file `test_plot.m' "

this happens for all the files that I've either downloaded from the internet, cut-copy-paste
or written them myself on emacs.Is there something i've done wrong?

Another question,are there any active communities dedicated to octave?i couldnt find any on google.is it because the coding is the same as matlab,so most users go to their websites?
