Should scalar divided by matrix be allowed?

@bsxfan

My argument in favour of more generally allowing the division of scalars by matrices is therefore one of consistency .

In the name of consistency, instead of extending it, I would suggest removing the pseudoinverse / magic for vectors. It is a bad pun, and just causes confusion. Cf

Feature or Bug? - Divide by zeros: 1/0 vs [1]/[0]

Before I open an Issue, I would like to discuss this question. The core of the question is the following difference: julia> 1 / 0 Inf julia> [1] / [0] 1×1 Array{Float64,2}: 0.0 In my method this lead to a problem as discovered here, because I use the left division with a non-square matrix, which can be full of zeros in some special situation. I supposed that as a tends to zero [1]/[a] tends to infinity julia> [1] / [0.01] 1×1 Array{Float64,2}: 100.0 julia> [1] / [0.001] 1×1 Array{Float64,2…

Users who want a pseudoinverse should explicitly ask for it.

Also, are you aware of LinearAlgebra.I? Eg (2*I)/randn(3,3) etc.
