Matrix Multiplication Introduction
A matrix is an
ordered rectangular array of numbers. A matrix with
m rows and n
columns has a size of m * n.
The entry in the ith row and
jth
column is denoted by
aij.
The three laws for
matrix multiplication:
If the products and sums are defined for the matrices A, B, and C, then:
1. (AB)C=A(BC) (associative law)
2. A(B+C)=AB+AC (distributive law)
The following is an example of a matrix:
P=
| 320 | 280 | 460 | 280 |
| 480 | 360 | 580 | 0 |
| 540 | 420 | 200 | 880 |
Size(P) = 3x4
