In numerical recipes is routine for it but if we want to write it from scratch i found reduction to Hessenberg by Gaussian elimination (Householder reflections would be better but I havent found how to effectively multiply matrix by Householder reflections) I derived multiplication by rotation matrices G from the left and G^{T} from the right which allowed to write QR decomposition But which shifts should I use How to use deflation QR metod can be done in place but how to do it

That tail function didn't work, it said "make; no targets specified and no makefile found". What should I do

My major is general physics and I plan to do a PhD in physics related to quantum mechanics. I’m eager to learn anything related to my future career. Luckily the YT algorithm recommended a video of this series to me this morning! Thank you!

Thank you so much dude. My professor somewhat went over how to do this in his lecture with the 1st degree equation of a line, but there was basically 0 material on how to do it with polynomials. This makes a ton of sense and helped me out.

I don't know whether as an engineer my brain just works better with this or I'm just dumb, but this is making my grad class math make sense.

But this is the same proof as the Cauchy's Integral theorem. That means they're the same right?

Is it a bad idea to let the curve C be a function of the form r = a(t) + i * b(t), a<=t<=b. And then integrate the real and imaginary integrals from t = a to t = a, because of it being closed, and then using the fundamental theorem to argue that the result should be zero.

@Channel-zb1fi 5 ай бұрын

Also the Green's theorem says that the integration over a boundary is equal to the integral over the domain, given some conditions. So should we not make the assumption that the contour can be continously deformed so its boundary perfectly fits with the boundary of the analytic domain, D. Since the original integration is done over the boundary of the domain C which is obviously a subset of D. So C would have to be made equal to D in order for Greens theorem to apply for the domain D.

Very helpful, thank you! Bounding the integral on the upper arc of the semicircle to show that it goes to 0 in the limit takes some extra work, though.

Which version of heasoft have you installed, 6.28 or 6.33 ??

@nspace-cowboy 3 ай бұрын

My guess is since the comment was 2 months ago it was probably 6.32. The same steps for 6.28 will apply for 6.33.

What about the convergence or real integral in the disk where we convert and integrate? If real integral doesn't convergence in the disk, it's impossible to do next steps.
