A symbolic representation of a matrix is called symbol of a matrix.

A matrix is symbolically expressed by using two types of brackets.

1.

Square brackets are most commonly used to represent a matrix symbolically in matrices.

$\left[\begin{array}{cccccc}& & & & & \\ & & & & & \\ & & & & & \end{array}\right]$

The elements of the matrix are arranged in number of rows and number of columns within the square brackets to represent a matrix in mathematics symbolically.

**Example**

$\left[\begin{array}{ccccc}4& 9& 1& 0& 6\\ 2& 4& 6& 8& 9\\ 1& 3& 2& 5& 7\end{array}\right]$

2.

Alternatively, round brackets can also be used to represent a matrix symbolically in matrices.

$\left(\begin{array}{cccccc}& & & & & \\ & & & & & \\ & & & & & \end{array}\right)$

The elements of the matrix are displayed within the parentheses to represent a matrix symbolically by using round brackets.

**Example**

$\left(\begin{array}{ccccc}4& 9& 1& 0& 6\\ 2& 4& 6& 8& 9\\ 1& 3& 2& 5& 7\end{array}\right)$

Either of them can be used to represent a matrix symbolically in mathematics.
