## Welcome to Math 170A (Lecture A, Winter 2023)

This page supplements materials to *``Introduction to Numerical Analysis: Linear Algebra''*

Linear algebra and in particular *numerical* linear algebra is a cornerstone of modern scientific computing. As such this class
involves a valuable amount of numerical reasoning in connection with practical methods.
One may use the materials to further learn about nonlinear numerical analysis in Math 170B or even use them as tools to numerically solve problems from research, industry and applications
accross a variety of different subjects.

Because of this, *algorithms* and *computer implementations* are important components of the class.
The examples and textbook are in [**Matlab**] (available for free to UCSD students), yet
in principle you are free to choose a language you like.

### Memo to the student:

Remember, this class is here to help succeed in learning the subject.

- •Homework problems will help prepare for Quiz, Midterm and Final questions
- •Being active in Lecture, Discussion and office hours will help to learn
- •Ask for help when you need help to learn the materials
