In StaticArrays 1.7 broadcasting with static arrays was improved: JuliaArrays/StaticArrays.jl#1220 This fix implies that in some cases in newer versions now a static array is returned where in older versions incorrectly an
Array
was returned.In ForwardDiff this breaks the
eigen
definition which uses an in-place method_lyap_div!
to computeA ./ (l' .- l)
(with diagonal entriesA[i, i]
). This PR fixes the problem by replacing it with a_lyap_div!!
method that, following the bang-bang notation, falls back to an out-of-place implementation and only uses an in-place method for arrays that are known to be mutable such asMatrix
orStaticArrays.MMatrix
.Fixes #690.
Fixes #702.
