Multiplying a matrix by a scalar is a simple yet powerful operation that involves multiplying each element of the matrix by a single number, known as the scalar. This operation is often denoted as A × k, where A is the matrix and k is the scalar. For example, if we have a matrix A = [2 4; 6 8] and a scalar k = 3, then the product A × k would be [6 12; 18 24].
