The nomenclature typically is:
Scalars are 1x1
Vectors are 1xN or Nx1
Matrices are MxN
Arrays are typically 3D or more, MxNxPx...etc

And just to clarify: "array" covers all of the varieties.
It is like a "point" is a particular example of a "line", and a "line" is a particular example of a "rectangle", and a "rectangle" is a particular example of a "hyperrectangle", with all the levels above that also being referred to as "hyperrectangle" -- so you could use "hyperrectangle" to refer even to something that later turned out to be a point.
In practice, though, it is not uncommon for people to use "matrix" in MATLAB even when they mean a 3D or more array.
