It can have multiple columns but there is just a single row present in a row matrix. In this chapter, we will typically assume that our matrices contain only numbers. Indeed, two very important vector spaces are associated with matrices. Lensemble des matrices a m lignes et n colonnes et a coefficients reels est note. From the definition it is obvious that if the order of a is m x n, then the order of a t becomes n x m. The matrix obtained from a given matrix a by changing its rows into columns or columns into rows is called the transpose of matrix a and is denoted by a t or a.
