Row Matrix (Row Vector)
Row matrix or row vector is a matrix with only one row, as illustrated by the following
matrices :
(
a
)
B
1 × 3
=
[
1 0 1
]
(
b
)
B
1 × 4
=
[
1 3 2 − 1
]
Column Matrix (Column Vector)
A matrix with only one column is called a column matrix or column vector . The following
are samples of column matrices:
( a ) L
3 × 1
=
[
1
0
3
]
(
b
)
L
4 × 1
=
[
3
2
1
0
]
Square Matrix
A matrix with equal numbers of rows and columns is called square matrix . The m x n matrix
is square, if and only if, m = n . The examples of square matrices are as follows:
(
a
)
S
2 × 2
=
[
− 1 2
− 4 0
]
( b ) S
3 × 3
=
[
3 2 1
3 1 0
2 1 4
]
The elements on the main diagonal of any given square matrix are all the elements which lie
from the upper left corner to the lower right corner. The main diagonal elements for matrix
S
2 × 2
above are –1 and 0. While, the main diagonal of matrix
S
3 × 3
are 3, 1 and 4.
