python numpy prototype project 01 intro to linear algebra

introduction to linear algebra with numpy: prototype project 01

overview

linear algebra is a branch of mathematics that deals with vectors, matrices, and systems of linear equations. in this tutorial, we will explore how to use numpy, a powerful library for numerical computing in python, to perform various linear algebra operations. we'll go over how to create and manipulate vectors and matrices, as well as how to perform operations such as addition, multiplication, and solving linear equations.

prerequisites

before starting, you should have the following:

1. python installed on your machine (preferably python 3.x).
2. numpy library installed. you can install it via pip:


getting started with numpy

first, let's import the numpy library:

creating vectors and matrices

vectors

matrices

basic operations

vector addition

you can add two vectors element-wise:

matrix addition

similarly, you can add two matrices:

scalar multiplication

you can multiply a vector or a matrix by a scalar:

dot product

matrix multiplication

solving linear equations

one common application of linear algebra is to solve systems of linear equations. we can represent these equations in matrix form \(ax = b\).

example: solving a linear system

consider the following system of equations:

1. \(2x + 3y = 5\)
2. \(4x + y = 6\)

we can express this in matrix form as \(a \cdot x = b\), where:

- \(a = \begin{bmatrix} 2 & 3 \\ 4 & 1 \end{bm ...
