Can someone, by any chance, have look at this math.stackexchange.com/a/102888/59219 ? In particular, why does this equation $ \lim\limits_{h\to 0}\frac{\overline{f(\overline{z+h})}-\overline{f(\overline z)}}{h} =\lim\limits_{h\to 0}\overline{\left( \frac{f(\overline z+\overline h)-f(\overline z)}{\overline h} \right)} $ hold?
@SohaibI Not my area of expertise. Looks like you can't. Determinants don't even make sense over non-square matrices. At best you could perhaps use some of the matrices from a SVD, as a rough non-expert guess.
I was wondering how to find $e_r$ using $e_x$ and $e_y$ as you can see in the scheme:
So what I really want is to prove that:
with a deep proof using maths
@Zibadawa Thanks. I found another method using cholesky factorization that works. But now an error pops up saying matrix must be positive definitive.
My 60 x 120 matrix has currently elements from -1 to 1 with two rows columns as completely zeroes. If I scale it between 0 and 2 will it have an impact on my overall result?
Is there a standard technique to prove an ideal is prime in a multivariate polynomial ring? Specifically, I'm trying to show the principal ideal generated by $y^2-x^2(x-1)$ is prime in $F[x,y]$ where $F$ is an arbitrary field.
