Matrix Multiplication Real World Example

[TheBiggerNoise]

I've said it before, but boy do I wish your channel was around when I was helping my kids through their math courses. Your explanations are so clear and easy to follow.
I'm watching to experience all the "hey, I used to know that!" moments.

Man I love that we touch on matrixes here, It's been 20 years since my college maths, I had forgotten pretty much all about it. The real-life example is great too

[rileypeterson]

Made it all the way through college linear algebra without really knowing this… somehow this 5 minute video is more helpful than a college course 😂😂

[kurtlindner]

We didn't put a box around anything, I'm freaking out!

This is one of those situations where I remember learning about matrix math in college, doing well enough in the class, but not knowing at all how to apply it to anything. Now that I've been in my career for a couple decades now, I can now think back on many situations where I could see how this could have helped with data analysis and reporting.

Thanks for showing the example at the I was trying to figure out what this could possibly be used for.

[fourcloveredleaf]

Brilliant explanation, the real world example made everything click for me

[trumpetbob]

That example was spectacular! I was learning this stuff but while I understood the rote mathematics, I never understood the why of what was done. Thank you!

Chatgpt is just a lot of matrix multiplications

[davidsiegel]

Thank you, matrix multiplication makes so much more sense now.

[preetdg]

Thanks :), I learnt a new concept that I mugged up earlier ...

[penguinlover]

Thank you for the explanation. My brain is happy. How exciting.

[farmcat]

Thanks! I wondered why matrices were needed for an advanced degree in a statistics-related subject.

[malle_yeno]

My math career would have benefited greatly if someone had told me even once what matrix multiplication is good for, rather than just how to do it. Like this makes so much sense now.

[m.i.c.h.o]

Relearning matrix multiplication... how exciting!

[kmjohnny]

A great way I saw matrix multiplication is to put the 1st one to the left, the 2nd one to the top - this way I'll see which rows should be multiplied with which columns.

[clifh]

the real world example simply blow me out

[troybaxter]

Another specific engineering example would be circuit analysis. It's been a while since I've done it, but you can use it to solve Kirchoff's Voltage Laws.

[antoniovlassa]

I have an engineering degree and only now understood the real practicality of matrixes. Apples and oranges monday through wndnesday is a lot easier to visualise than the movements of a robotic arm or whatever we were supposed to understand that off of

[KallMeSam_]

Begining: he's just multiplying each number with the corresponding number in the other box
Middle: Wait, why is he adding
End: Never mind, I guess im not learning this
