AE 501: This was an extremely useful refresher - especially for matrix multiplication and special matrices

[maggies]

AE 501- WOW - I spent a couple hours reteaching this to myself yesterday - you explained it so much clearer and quickly than the textbook!

[ryanmeinhardt]

AE-501 : Great crash course of everything i forgot about matrices.

[Julia_Westfall]

AE 501: I really appreciate you used the .* notation to explain element wise method! I thought of MATLAB right away and it gave me a great resolution as to why I was at war with myself trying to recall marix multiplication being one or the other (standard method or element wise). Huge shout out to the flipped classroom method with all of the videos I can take at my own pace and ask questions at office hours REALLY helps my learning. I am so excited to take this class! Thank you!

AE 501 - Nice refresher on matrices and their basic operations

[elijahleonen]

AE501: Really helpful and straight forward video of the purpose of matrices along with it’s operations.

[JonathanRiosRoman]

AE-501B: Excellent refresher, clear and concise. Thank you professor!

[JulieWarchol]

Thanks for the refresher! I missed doing this kind of math. Looking forward to this quarter in AE 501.

AE 501: This video is a helpful refresher on matrices

[Andrew_Bruns]

AE501- Definitely helpful for a reminder on rules for matrix multiplication and matrix transpose.

[AE501] I'm glad to have had this video as a reference this quarter, this topic can get tricky sometimes

[PathwaytoEngineeringDegree]

I took Matrix in college few yrs ago and totally forgot the basics and therefore this video was refreshing for me. Thank you covering all of the basics without treating us like idiots hahaha.

[AdamYousri-mt]

AE501: this was a great intro to matrices; it's been a while, and I definitely needed the refresher.

[KevinKdep]

AE501: This is an excellent lecture video! It really is a great refresher for me after I have taken linear algebra almost 30 years ago. :)

[nizomjonnazirov]

wonderful Mr Lum thanks for your efforts

[AlejandroMartinez-nvri]

AE501: The uppper/lower triangular matrices were new to me and not something I remember from my undergraduate math courses, im curious what type of use cases they would be good for. Great refresher on matrices, thank you!!

[lizahaddad]

Please could you add a video about sliding mode and it's implementation in MATLAB.Thank you

[AlexanderLRisher]

Good Review, Thank you.
