This is a nice summary of concepts

Now this is some extraordinary stuff out there wrt la

That has got to be useful for something XD for so long I've always even wondered why we care about "row space" as a thing, at all, but this is interesting already as I seek the answer, that they exhibit such properties as this!

I self studied this 2year ago. I havent found any applications in my Electronics engineering yet (sophomore now). But I'm starting to see some applications in optic lens combination problems. Also some in portfolio risk/profit optimization, which is cool and satisfying to be able to FINALLY use linear algebra

Looks like there is a sign error for the vector spanning the rowspace of a in computation of the dot product of the rowspace and the null space

ok? i am a littl comfuse
