WebThis is referred to as matrix multiplication. Scalar Multiplication. Because the expression A+A is the sum of two matrices with the same dimensions, a matrix A can be added to itself. We end up doubling every entry in A when we compute A+A. As a result, we can interpret the expression 2A as instructing us to multiply every element in A by 2. WebTo multiply a matrix by a scalar, also known as scalar multiplication, multiply every element in the matrix by the scalar. For example... 6 ∗ A = 6 ∗ ( 1 − 5 4 2 5 3) = ( 6 ∗ 1 6 ∗ − 5 6 ∗ 4 6 ∗ 2 6 ∗ 5 6 ∗ 3) = ( 6 − 30 24 12 30 18) To multiply two vectors with the same length together is to take the dot product, also called inner product.
