A matrix is a rectangular array of numbers or functions arranged in rows and columns. • Rows: Horizontal lines of elements. • Columns: Vertical lines of elements. • Order of Matrix: A matrix with 'm' rows and 'n' columns has an order of m × n (read as 'm by n'). • Total Elements: Equal to m × n.

A matrix is an ordered rectangular array of numbers or functions arranged in rows and columns.

Key Concepts: • Order of Matrix: A matrix with 'm' rows and 'n' columns has an order of m × n. • Elements: The numbers inside a matrix are called its elements, denoted by a_ij (row i, column j). • Total Elements: Equal to the product of m and n (m × n).
