Sort and dims=1 for vector input

Julia treats vectors as different than n x 1 matrices. For example,

julia> x = rand(4, 1) # 4 x 1 matrix
4×1 Matrix{Float64}:
 0.5699429434936178
 0.38264907855330454
 0.2974011813965416
 0.9032771294647794

julia> sort(x; dims=1) # works fine
4×1 Matrix{Float64}:
 0.2974011813965416
 0.38264907855330454
 0.5699429434936178
 0.9032771294647794

So it’s not about if size(x,2)==1, it’s about the type of the object. Usually code where x is sometimes a vector and sometimes a matrix is avoided (it’s usually type unstable), but if y is a vector, you can reshape it to be an n x 1 matrix via

julia> y = rand(4)
4-element Vector{Float64}:
 0.2646642144471312
 0.5108444025487056
 0.17038220190741749
 0.6299368977104578

julia> reshape(y, :, 1)
4×1 Matrix{Float64}:
 0.2646642144471312
 0.5108444025487056
