A system of representing a matrix by a symbol is called representation of a matrix.

A matrix with its elements are expressed in matrix form by using either square or round brackets.

$\left[\right]$

(or)

$\left(\right)$It consumes more time to express any matrix more times in mathematics. Instead, matrices are represented by the symbols. Matrices are usually denoted by symbols such as alphabetic letters

$A,B,C$and etc.

Therefore, consider a letter and equate it to the matrix.

$R=$

Now, just write the alphabetic character

$R$instead of writing the entire matrix in the matrices system of mathematics.
