Winter 2024 - Pretty solid class and professor. It is just a tad bit tougher than 151A, which was already super easy. It's cool, and he explains well. He has a lot of academic experience which always is nice. I would've liked a bit more real life applications, rather than more proofs/plain computation. It delves deeper into linear algebra, interval of stability & timesteps of numerical methods, systems of ODEs, iterative methods, boundary problems and least squares. There was no curve this time (I think), it was around 50% As and A-s, which is pretty solid. I think there were a lot more A-s this time, slightly worse than previous quarters.

Winter 2021 - Very passionate professors that writes out his lecture notes instead of using the textbook. Do a way better job at making theoretically messy concepts from the book more comprehensible. Overall his tests are fair, not easy but neither is all the material in the course. Really helpful in office hours, and homework accounts for 50% of the grade, which is nice!

Winter 2020 - If you want someone to badly read the textbook to you, this is your man. I thought numerical analysis was pretty interesting before I took this class. It's not that he doesn't care, I think. He is just really bad at communicating information, even though he can speak English just fine. I would describe lecture as awkward and confusing. I tried to make a habit of reading the relevant textbook section before going to class, so that I would actually get something out of going. But then I had some unexpected life circumstances put me behind and I just stopped going to class. You don't really need to when the textbook is just as good, and more clear. He made attempts to clarify by posting slides and reviewing material multiple times, and it helped a little. Every week, the homework questions were unclear in what exactly they were asking for. So discussion became a lifeline, as well as emailing the TA. And the midterm was even worse. Both sections of the class stared in horror at the test for 50 minutes, trying to just understand the questions. But then the class average turned out to be like an 85? Honestly everything turned out well, so I can't be mad. Generous grading, reasonable accomodations and emailing. It just felt awful and boring to go through the whole process

Spring 2021 - The class is very good and straightforward! The tests are not too bad, and he grades way too generous. The homework is fun (you should go to discussion sections to learn Matlab!). You don't have to watch lectures to do well in this class since everything is in his notes. Overall, a very chill class during the pandemic, the only thing that I would slightly complain is the slow grading for the finals.

Spring 2022 - Avoid this professor. I have nothing good to say about her. Huang is one of the worst lecturers I’ve had in my 3 years at UCLA. She often discusses topics without motivating them, making it tremendously difficult to follow along. She is also one of the least helpful people I have met in general. She is short spoken and, according to one of my friends who has taken another class with her, will intentionally withhold information from you if she does not like you. I also once asked her a question during an exam, and she took the extra time and effort to utter a belittling and rude remark about my capabilities. The midterm was very similar to the homework assignments and relatively manageable. On the other hand, I felt like doing well on the final relied too much on keeping up with tedious algebra and remembering easily forgettable facts from pre-requisites. I would really recommend taking this class with another professor if you get the opportunity.
