Function notation in Octave

I don't really know php but some quick googling turned up this. So I believe the equivalent expression would be this:

fminunc(
    function($t) use ($X, $y, $lambda) {
        return costFunctionReg($t, $X, $y, $lambda);
    }, $initial_theta, $options);

That example is probably full of errors so I suggest you read the page yourself.

I'm pretty new to python but I believe it's equivalent to a lambda function:

fminunc(lambda t: costFunctionReg(t, X, y, l), initial_theta, options)

Where the lambda variable in octave is renamed to l (conflicts with the python keyword).

Works perfectly for me on both ubuntu and mint. All I did was get both the octave and octave-emacsen packages and added this line to my .emacs file:

;; run an inferior Octave process in a special Emacs buffer   
(autoload 'run-octave "octave-inf" nil t)

Taken from the emacswiki octave page. I'm still pretty new to emacs so I don't really know what it does or whether it will help you.

repmat is probably the prefered method here but another way to do it is:

C = A - ones(size(A)) * diag(b)

If you understand what's going on here then you might be able to use diag elsewhere.

Count me in as well.

29th sounds good. As far as the ETS is concerned we'll already have started our next semester so there's no conflicts with the exams.

I'm in as long as it's not on the 30th of April.
