Table of content1. Error Analysis
This /cs-notes/nm webpage is a hobby project that aims to create a collection of notes on numerical methods (and analysis) in an orderly fashion. These notes are inspired by the lecture given by Tomasz Romaczukiewicz, some books, and some web articles, but customized on my own. I’ll be adding (or appending or amending) the contents suitably related to this field and will polish them time and again. I hope this work will be helpful for you too.
We’ll be using Python v3.x for all the coding examples. This language is easy to get you to start, and prototyping the concepts. But, for numerical intensive work, I recommend C++ (or Julia or rust). For illustrations via animation, I’ll use manim or matplotlib. While replicating the examples, I recommend using Jupyter Lab or vscode plugin for Jupyter. Since I’m trained to become a physicist so, some of the examples will be related to physics. I hope you don’t feel discouraged if your interest is not in physics. But, you’ll learn so many things related to CS, maths, statistics, and finance which is a win-win situation for you 😃.
# matplotlib settings from matplotlib import rcParams # https://matplotlib.org/stable/api/matplotlib_configuration_api.html#matplotlib.rcParams import shutil # https://docs.python.org/3/library/shutil.html rcParams['figure.dpi'] = 120 rcParams['figure.figsize'] = [12,6] rcParams['font.size'] = 12 rcParams['axes.grid'] = True rcParams['text.usetex']= True if shutil.which('latex') else False # Checks if latex is installed. Since, matplotlib.checkdep_usetex(True) will be depreciated in Python >=3.6. So, we use python's standard library named shutil instead.
