A matrix is a rectangular array of elements with rows and columns denoted by the numbers of rows (m) and columns (n), with elements identified by subscripts. Understanding matrix dimensions is crucial for correctly identifying elements and operations like scalar multiplication involve multiplying each element by a single real number.
