The given matrix is
Row matrix of order 1x3
Row matrix of order 3x1
Column matrix of order 1x3
Column matrix of order 3x1
Matrices, order of matrices, row and column matrix -
A set of numbers (real or complex) or objects or symbols arranged in form of a rectangular array having m rows and n columns and bounded by brackets [?] is called matrix of order m × n, read as m by n matrix.
E.g for m = 2 and n =3, we have order of this matrix is 2×3
Column matrix: A matrix containing only one column is known as a column matrix. So a matrix is said to be column matrix when n = 1.
E.g :
A matrix that contains only one row or one column is also known as vectors i.e. row vectors and column vectors.
-
Here m=3 and n=1, therefore, order or given matrix is 3x1
hence, the correct option is (d)
