The transpose of a 1x1 matrix should equal itself

[hochB]

The transpose of a 1x1 matrix is itself, right?
Julia disagrees.

julia> A = [1]
1-element Array{Int64,1}:
 1

julia> A == A'
false

[fredrikekre]

A is not a matrix, its a vector:

julia> A = fill(1, 1, 1)
1×1 Array{Int64,2}:
 1

julia> A == A'
true

[hochB]

Is this behavior also expected?

julia> A = [1 2 3]
1×3 Array{Int64,2}:
 1  2  3

julia> B = [1, 2, 3]
3-element Array{Int64,1}:
 1
 2
 3

julia> A'
3×1 LinearAlgebra.Adjoint{Int64,Array{Int64,2}}:
 1
 2
 3

julia> B'
1×3 LinearAlgebra.Adjoint{Int64,Array{Int64,1}}:
 1  2  3

julia> A == B'
true

julia> A' == B
false
