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

    THESE VIDEOS ARE LIFECHANGING. thank you for doing what a professor from the #6 university in the US couldn't.

    Hi James , many thanks for all of these tutorials it is amazing I don’t know how would I thank you I have been struggled for more than two weeks to understand what is the null , how to calculate the kernel and the image and I could not reach an answer please keep up

    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?

      Yes h will only have that particular value in all vectors that are in null space
