The way I understand it, Julia has no syntax for single column (size (n,1))
matrix literals.
Of course
[1 2]
[1 2;
3 4]
both create matrices, and I would have hoped that
[1;]
[1;
2]
would as well, but they create vectors instead. I still hope that this can
be changed at some point (seem to remember that it has been discussed, but
can't remember where).
But given the current state, what is the recommended way to get something
like matrix literals?
I could define a function
mat(a::AbstractVector) = reshape(a,(size(a,1),1))
mat(a::AbstractMatrix) = a
and then use e.g.
mat([1;
2])
I first tried with
mat(a) = convert(Matrix, a)
and then
mat{T}(a::AbstractArray{T}) = convert(Matrix{T}, a)
but those both gave method errors. Shouldn't those conversions be defined?
I know that I can use double transpose [1;]'' but given the discussions
about dual vectors, that might not be future proof.
