Linear Algebra - Lecture 28 - Null Space of a Matrix

In this video lecture, I define the null space of a matrix, and work through several examples.

On behalf of CS students everywhere, your lectures are fantastic and invaluable. Don't know what I'd do without them.

Hello sir, first of all thank you so much for these lectures they are so clear and easy to follow. Im finding them really useful especially given the pandemic and online learning on a state university in spain is hard. Secondly, are you using any textbook in particular? Im finding it tricky to find good simple ones :)

Thank you for your effort

Hi, first i would like to thank you for sharing your amazing lecture.

I would like to asked if the null space is referring to the turquoise plane in 3:28 of lecture 11?

just to be clear at 4:37 if h did have different values from those equations, would that mean that u cant be in the null space of A?
