🌿 CASE 1 🌿
I finished the Introduction to Linear Algebra course. I've finally mastered it. Throw me any problem and I can solve it flawlessly. But... I need to do the singular value decomposition of a 100 x 100 matrix right now. Seriously... I've mastered linear algebra, but this problem is going to take forever.🌿 CASE 2 🌿
Professor: Approximate this data with a quadratic function by tomorrow.
Student: Okay, I understand. How many data points are there?
Professor: 40,000.
student: ??
Professor: Oh, while we're at it, how about fitting a+b*sinh(x)+c*Log(x) as well? Can we do it quickly?
student: ?????????
🌿 CASE 3 🌿
Now that I'm not in college, I can't use Matlab... It's too expensive... Ha... But how do I solve matrix equations...? I'll have to solve some more in the future, but is there any way to do it?
Let's solve various matrix calculation problems using NumPy and SciPy.
To quickly solve matrix calculation problems, you need to use the NumPy and SciPy libraries in Python. Have you ever wanted to solve matrix equations using a computer? Want to find eigenvalues? Or do you need these functions right away?
In this course, you'll use Python's SciPy library to solve a variety of matrix calculation problems. Even if you don't know Python or have a basic understanding of introductory linear algebra, the content is designed to help you apply the knowledge immediately after taking the course. Don't worry, join us!
Learning Objectives 📜

Check before taking the class! ✒️
- You can take the course even if you do not have any specialized knowledge of Python.
- Lectures and practical training are conducted simultaneously.
- For those who plan to use the Lapack library in the future, I will explain what Lapack functions are related to the functions used in the course.
- In this lecture, we will not learn numerical analysis theory related to matrix calculations.
Questions to ask before taking the class!
Q. Is it true that matrix equations can be solved on a computer?
A. Of course. It would be stranger if it wasn't solved by computer!
Q. I need to find the eigenvalues of a large matrix right now. How do I do it? I can't solve it manually 😭😭
A. Don't worry. You can get it with just a few lines of Python code. This course is for you.
Q. I have no programming experience... but I want to solve linear algebra problems on a computer!
A. Welcome! It's easy to follow.
Q. I heard Python is slow... Isn't it impractical to learn it?
A. The SciPy functions we'll learn utilize functions written in Fortran (developed over decades!). They offer speed and accuracy that are sufficient for practical use.
Q. Where did you hear that... people usually write the code themselves...?
A. There are linear algebra-related functions that have been developed over decades, not just years. Just knowing how to use them can be a huge help in your life.

76% enrolledI am writing my first review on the 25th/29th class, 10h33m class time. I am not a person who usually writes things like this, so I think I should write it now so that I don't procrastinate. Reason for taking the class: While studying ML, I needed to learn Numpy slicing correctly, and while looking around the course, I thought it would cover it, so I took the course. Review: I needed to learn Numpy slicing correctly. I did not take Beomhee Cho's linear algebra lecture in advance, but I had no problem following it. If you follow this course calmly, you will learn how to use Scipy's linalg functions sufficiently. The explanations and examples of how to use functions are thorough, and the instructor explains them in detail without making students think, "Obviously, I know that." That is why I want to listen to Beomhee Cho's linear algebra lecture that you posted before. (I thought they would give out a discount coupon if Infraon was renewed... but they didn't. Haha)

Thank you for your valuable review!!ㅎㅎ Since this is a course that I created without a textbook or a given curriculum, I personally have a lot of affection for it because I put a lot of effort into it. If you see any parts that are lacking or need to be updated while watching the course, please send me a message or email me feedback at any time and I will do my best to reflect them. There may be parts that I didn't even think of, so if you actively give me opinions, the course can be updated(!) and revised. (I'm currently creating another math-related course. I hope you'll show a lot of interest in the future ㅎㅎ)

45% enrolledAt the beginning of the lecture, you said that if you get a chance, you will also open a course on the legendary language Fortran. Please do open it! It is necessary for graduate schools that use Fortran.

I will definitely try to make it in the future as soon as I have time. Thank you!
