I'm working at my Master's Thesis in Probability Theory. I'm missing a bunch of basic knowledge in LA tho.

While we're at it: if lambda is the spectral radius of A, is it true that |Av| is upper...

yes exactly. lambda is the perron-frobenius-eigenvalue, while M1 is the outer product of lambda's eigenvectors, scaled so that it is idempotent. obviously N and M1 need to be orthogonal because if...

u wot m8? why does (3.5) hold? I don't even know where to start looking

smh @ Juventus logo, looks like the icon for some smartphone app

sup fellas, this is regarding the following exercise, especially the second inequality:

Our definition of Rademacher complexity:...

your first question:

|x| is x for x>=0 and -x for x <0 so if you come from the left the lim is -1 and from the right it's 1. so it's undefined

can't answer the second question tho as I don't...

got my Bachelors diploma today. Shout outs to MiscMathematician and all the others

so you have an x and gut it into g, then it becomes 3x. Then you put that into f, that means you take f(3x)

how did you get the idea to put -3 as domain?


so you got the function right. now...

Handed in my Bachelors Thesis today, feelsgoodman

pls respawn, I'm trying to figure ut an example but it just doesn't work out

whattup fellas, can anybody give me an example for the inhomogenous heat equation on (0,1)² where v(x)=0? Preferably something simple

I had to make a program that...

Hey fellas, it's me again with some fresh matlab questions

say I have a discrete approximation u_h of a function u where the approximation looks like this

Wall goes down in E10 I think

das it mane

the last part is all but confirmed. 1000% sure he will murder her

I have a follow-up question: if I want to add a point in there, for example at (0,0), I can use

plot(0,0,'r.','MarkerSize',20)

but how can I give the point a name (p1 for example)?

I love you man

a stupid question here: Can I draw something like this in MATLAB? If yes, how?

Hey fellas, I'm currently working on my Bachelor's Thesis and right now I'm at a place where I need to numerically solve a system of ODEs

a'(t)+Aa(t)=Bb(t) and a(0)=y

where A and B are...
