Study Notes
Matrix and Its Properties
- A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.
- The rank of a matrix determines the maximum number of linearly independent rows or columns, and can be used to identify the solvability of a system of linear equations.
System of Linear Equations
- The consistency of a system of linear equations indicates whether the system has a unique solution, no solution, or infinitely many solutions.
Eigenvalues and Eigenvectors
- The purpose of finding eigenvalues and eigenvectors of a matrix is to understand the linear transformation represented by the matrix, and to identify the directions in which the matrix stretches or compresses.
- The power iteration method is used to obtain the largest eigenvalue of a matrix, which is an efficient method for finding the dominant eigenvalue.
