Description

lowrankupdate / lowrankdowndate are not defined for StaticArrays

AL = randn(SMatrix{4,4,ComplexF64})
A = AL'AL
A_chol = cholesky(Hermitian(A))
a = randn(SVector{4, ComplexF64}) / 100
lowrankdowndate(A_chol, a)
# ERROR: MethodError: no method matching lowrankdowndate(::Cholesky{ComplexF64, SMatrix{4, 4, ComplexF64, 16}}, ::SVector{4, ComplexF64})

Research direction

Reproduce the supplied Julia example with StaticArrays and inspect the existing lowrankupdate and lowrankdowndate implementations and related tests. Define the missing StaticArrays methods with behavior consistent with the existing implementations, then add coverage showing the Cholesky example works for SMatrix and SVector inputs.
