Hence Matrix is an arrangement of rows and columns being enclosed by brackets usually it can be of any shape like 1×1 2×2 3×3 2×3 1×2 1×4 3×4 etc.
Notation Matrices are usually denoted by uppercase letters (e.g., A,B,C), and their elements are typically denoted by lowercase letters with two subscripts (e.g., aij where aij refers to the element in the i-th row and j-th column of matrix A).
Types of Matrices
1. Row Matrix
2. Column Matrix
