This is what you get by invoking the above-mentioned functions with matrix arguments whose element type `T <: Real`. -By default, the result is not quite in standard form, in that some -pair-blocks (and therefore rank-2 invariant subspaces) are not fully resolved. +By default, the result is in standard form, so +pair-blocks (and therefore rank-2 invariant subspaces) should be fully resolved. +(This differs from the original version in GenericLinearAlgebra.jl.) -If the optional keyword `standardized` is set to `true` in `gschur`, a -standard form is produced.

Eigenvectors are not currently available for the "real Schur" forms.
