What Is a Line Matrix Printer?

In linear algebra, a row vector or row matrix is a 1 × m matrix, that is, a matrix consisting of m elements in a single row, denoted as A = (a ₁ a ₂ a _m ). Let A = (a ₁ , a ₂ , ... a _n ).

In linear algebra, a row vector or row matrix is of order 1 × m

To simplify writing column vectors, column vectors are sometimes written as row vectors and transposed.

Some authors also use the convention of writing column and row vectors to rows, but separating column vector elements with commas.

(1) The rank of the row matrix is 1;

(2) The transpose of the row matrix is a column matrix;

(3) Row matrix

Multiply to a real number;

(4) Column matrix
