In mathematics, a matrix can be defined as a rectangular 2-dimensional array consisting of elements such as numbers, symbols, or expressions. It exhibits a specific arrangement of rows and columns, allowing for efficient representation and manipulation of structured data. The matrix’s grid-like structure aids in various mathematical operations and applications.
An m × n matrix is referred to as such because it consists of m rows and n columns. The elements within the matrix are denoted by a, indicating that the element ‘a’ is located in the ith row and jth column. This notation allows for specific identification and referencing of individual elements within the matrix structure.
