At PHENIKAA University, I have the privilege of instructing various classes in Mathematics. As part of my role, I am currently crafting a series of comprehensive lecture notes to aid my students' learning experiences. Among these resources, I am diligently working on a concise set of notes (in Vietnamese) specifically focused on Linear Algebra, Analysis, Differential Equations, Probability and Statistics, and Numerical Analysis. Among these, "Linear Algebra" which I co-authored with Dr. Bui Xuan Quang, Dr. Phan Quang Sang, and Dr. Do Quoc Tuan is going to be published soon. My lecture notes "Numerical Analysis with R" will be freely available soon (a draft version is already available upon request).
Also, I compiled some MATLAB/Octave codes as well as R codes for my Numerical Analysis classes, which are available here.
