One could also remove all types and only rely on duck typing. Then one will
want to initialize r with something like zero(zero(x[1])+zero(y[1])). And
the same in the if statement. This function would run at the same. I still
like to specify types as this allows me to restrict input parameters.

in old Julia version works this code:

You can use the transpose .' instead of the conjugate transpose, i.e.
julia [Andreas,Noack,Jensen].'

Exactly. That's what I do quite often with complex line integrals, where
one vector is real: a [0,1]-parametrization of the curve, and the other
complex: the value of a complex function on the curve. And indeed, this
works very well for closed circle integrals in the complex plane, for
example
Hello!
I want to create a multidimensional array of dicts, say 4x4. My first guess
was to use the function fill()
julia my_array_of_dicts = fill(Dict(), 4, 4)
I want to include a new element to one of the dicts, say in position 2,2. So
julia my_array_of_dicts[2,2][somekey] = [somevalue]
but
You can use a list comprehension, so that you actually create 16
dictionaries.
my_array_of_dicts = [Dict() for i = 1:4 , y = 1:4]

Would it be more useful for fill() and fill!() to take copies of mutable
objects? I can't really see a use case for fill that fills an array with
pointers to the same object.

Hi,
I wonder how ready is julia to be used in iOS? For logic only? For call
obj-c/coccoa code?
First hurdle is getting Julia to run on an ARM processor,
see https://github.com/JuliaLang/julia/issues/3134
If Objective-C code has the same ABI as conventional C, then I imagine
Julia's ccall's should work the same
(http://nbviewer.ipython.org/gist/evanmiller/9022903 looks relevant?).

It's also possible to run an IJulia notebook from a server and access it on
iOS, either using a web service or by SSH tunneling.

Is there a reason why the following two calls to eigs order the eigenvalues
differently? The first `mat1` is numerically not symmetric but I would have
still guessed the ordering of the magnitude of the eigenvalues would be the
same as those for `mat2`?
julia A = rand(4,4);
julia mat1 = A.'
You can do:
[1, 2, (flag ? 3 : [])]
or:
tuple(1, 2, (flag ? (3,) : ())...)

Different LAPACK routines (and different algorithms) are used for

in ascending order, while the latter provides few guarantees about ordering.

Thanks Steven. I figured it was something like that. I was hoping that since
the non-symmetry was just numerical error I would still get the eigenvalues
sorted in the same order as the symmetric case. It does seem unsatisfying that
such a small numerical error can cause such different behavior

The Beaglebone Black is pretty beefy and fairly cheap if you are looking
