Testing if an object is a Matrix or a Vector

For a long time I used :

is_Matrix(A)
is_Vector(B)

but it is now deprecated. So I tried, like in https://ask.sagemath.org/question/975..., isinstance(A,sage.matrix.matrix.Matrix) which does not work.

What can I do ?

Does this one work?: isinstance(A,sage.structure.element.Matrix)
