Week 1
The Foundation: Matrices and matrix arithmetic
1.1: Introduction to Matrices
Matrices, which are essentially rectangular arrays of numbers, serve as fundamental tools in linear algebra, allowing for the representation and manipulation of systems of linear equations and transformations.
These notes cover the basics of matrices like rows and columns, types of matrices, and basic operations like transposes.
Matrix arithmetic, a core component of matrix algebra, involves essential operations like matrix addition, scalar multiplication, and matrix multiplication.
These notes explore the rules and techniques for performing these operations, ensuring that you understand the conditions under which they are valid and how to apply them to solve future problems.
