I'm with dbp on that one. To my book it is a matrix as well. A matrix can have one of the size reduced to 1. Wikipedia definition never restrict the size large or equal to 2.
Matrix backslash operator \ can be applied on matrices, vectors or scalars because they are all matrices.
Thinking a matrix must have a size larger than 1 is human, not mathematics.
