Matrix Basics and Types
- A matrix is an ordered rectangular array of numbers or functions arranged in rows and columns
- Order of matrix: m×n means m rows and n columns
- Matrix notation: A = [aᵢⱼ]ₘₓₙ where aᵢⱼ represents element in ith row and jth column
Matrix Operations - Addition and Subtraction
- Matrix addition/subtraction is only possible for matrices of same order
- Operations are performed element-wise
- Addition is commutative and associative
Scalar Multiplication and Matrix Multiplication
- Scalar multiplication: multiply every element by the scalar
- Matrix multiplication: only possible when columns of first = rows of second
- Matrix multiplication is NOT commutative in general
