Notes Matrices II 3 Matrix Multiplication 3 1 Introduction So far we have seen two algebraic operations with matrices, addition and scalar multiplication
We can multiply matrices A and B together to form the product AB provided the number of columns in A equals the Example of multiplying matrices 1
30 juil 2020 · These notes describe a few subcubic matrix multiplication algorithms that go To multiply two n×n matrices, we divide each matrix into 4
Goals p Multiply two matrices p Use matrix multiplication in real-life situations 4 2 Your Notes State whether the product AB is defined
The matrix A above, for example, has 3 rows and 4 columns, so its size is 3 × 4 Another operation is scalar multiplication: multiplying a matrix by a

For example, 4 1 3 2 −1 = 4 12 8 −4 Matrix multiplication The product AB of two matrices A and B is defined if and only
transpose, sum difference, scalar multiplication • matrix multiplication, matrix- vector product • matrix −3 −3 ] for example, to get 1,1 entry of product:
This matrix product is easily generalised to other row and column matrices For example if C is a 1 × 4 row matrix and D is a 4 × 1 column matrix: C = [ 2 − 4 3 2 ]
