Thanks @Jutho! :)
You're welcome. I assume the one travis error is unrelated? Sorry about the whitespace error at first; I edited online using Github, and indenting a blank line the same as the surrounding code lines seems to be the default. |
Hah, funny, yes, that test failure is unrelated. Looks like it's the |
* Make copyto!(A,I) work for rectangular matrices * add tests for `copyto!` add tests for `copyto!(::Matrix, ::UniformScaling)` * fix whitespace
Add a docstring for copyto!(::AbstractMatrix, ::UniformScaling) and document 1.1 changes.

Given that
Matrix{T}(I, (m,n))
works for rectangular matricesm != n
, I would also expectcopyto!(A,I)
to work. I often use this to initialize an existing matrix with ones on the diagonal, even if it is rectangular.An example is in LinearAlgebra, suppose you want to materialize the q factor in a QR decomposition. You might have two equally sized matrices
A
andB
lying around:I'll probably need to update some tests as well?
