Types of Matrices Based on Dimensions
1. Row Matrix
- A matrix with only one row is called a row matrix.
- Example:
\[\Large
Row\;Matrix\;C =
\begin{bmatrix}
4 & 7 & 9
\end{bmatrix}
\]
- Here, C has 1 row and 3 columns (1 × 3).
2. Column Matrix
- A matrix with only one column is called a column matrix.
- Example:
\[\Large
Column\;Matrix\;D =
\begin{bmatrix}
2 \\
5 \\
8
\end{bmatrix}
\]
- Here, D has 3 rows and 1 column (3 × 1).
3. Square Matrix
- A matrix with an equal number of rows and columns is called a square matrix.
- Example:
\[\Large
Square\;Matrix\;E =
\begin{bmatrix}
1 & 4 & 7 \\
2 & 5 & 8 \\
3 & 6 & 9
\end{bmatrix}
\]
- This is a 3 x 3 matrix.
