After discussions with SimonDansch, we decided it is better use a special type to do this, and so created FillArrays.jl I'm getting this working now:
BlockArray(Zeros(6,6), 1:3, 1:3)
from blockarrays.jl.
I think using Zeros
, Ones
etc has the same problem that is currently causes constructors in Base to change? What if I want oneunit
instead of one
. Is there a need for a new type in that case as well? Using types. to chose what value something should be filled with seems to be lifting up the value domain to the type domain.
from blockarrays.jl.
Then use Fill
: BlockArray(Fill(oneunit(Dates.Day), 6,6), 1:3, 1:3)
from blockarrays.jl.
Only 0
and 1
have special types as Zeros
and Ones
, with the latter being questionable. But Zeros
is distinguished because of sparse matrices.
from blockarrays.jl.
This almost works now that BlockArray(::AbstractArray, ...)
works. The remaining issue will be resolved via #40.
from blockarrays.jl.
