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. WebPart I. Scalar Matrix Multiplication In the scalar variety, every entry is multiplied by a number, called a scalar. In the following example, the scalar value is 3. 3 [ 5 2 11 9 4 14] = [ 3 ⋅ 5 3 ⋅ 2 3 ⋅ 11 3 ⋅ 9 3 ⋅ 4 3 ⋅ 14] = [ 15 6 33 27 12 42] More on …
