Description

Many of the Numerical Analysis courses focus on the theory and derivations of the numerical methods more than the programming techniques. Students get the codes of the numerical methods in different languages from textbooks and lab notes and use them in working their assignments instead of programming them by themselves.

For this reason, the course of Programming Numerical Methods in Python focuses on how to program the numerical methods step by step to create the most basic lines of code that run on the computer efficiently and output the solution at the required degree of accuracy.

This course is a practical tutorial for the students of Numerical Analysis to cover the part of the programming skills of their course.

In addition to its simplicity and versatility, Python is a great educational computer language as well as a powerful tool in scientific and engineering computations. For the last years, Python and its data and numerical analysis and plotting libraries, such as NumPy, SciPy and matplotlib, have become very popular programming language and tool in industry and academia.

That’s why this course is based on Python as programming language and NumPy and matplotlib for array manipulation and graphical representation, respectively. At the end of each section, a number of SciPy numerical analysis functions are introduced by examples. In this way, the student will be able to program his codes from scratch and in the same time use the advanced library functions in his work.

This course covers the following topics:

  • Roots of High-Degree Equations
  • Interpolation and Curve Fitting
  • Numerical Differentiation
  • Numerical Integration
  • Systems of Linear Equations
  • Ordinary Differential Equations
Who this course is for:
  • The students who currently study their first course in numerical methods and need to understand how the methods are coded in detail.
  • The students who need to create their own numerical analysis codes or use Python numerical libraries for their course, project or thesis works.

I am a doctoral researcher in Physics. I am used to coding in MATLAB for my numerics. The problem with MATLAB is its cost. I wanted a to learn a tool that would match my requirements while being free. I knew that python would be a great match and all I wanted was an excellent course to get into it. I got it here.
