Hi,

The following piece of code:

using LinearAlgebra, SparseArrays
size(svd(rand(3,3)), 1)

gives the error:

ERROR: MethodError: no method matching size(::SVD{Float64,Float64,Array{Float64,2}}, ::Int64)

You are comparing two completely different things. In Julia v0.6 size(svd(rand(m,n)), 1) is just the size of a length 3 tuple (so you might just aswell replace that with 3).

I see, missed that. Thanks.
