Hmm...
I figure it is not a command problem, but rather an installation
problem since a simple file with the commands below does not work
either.
function y = f (x)
y = cos(x/2)+x;
end
Any ideas what the problem might be? The error message is:
error: `x' undefined near line 2 column 9
error: evaluating binary operator `/' near line 2, column 10
error: evaluating argument list element number 1
error: evaluating binary operator `+' near line 2, column 13
error: evaluating assignment expression near line 2, column 3
error: called from `f' in file `/octave_files/f.m'
Sorry for spamming in this way...
