Need help with reduced row echelon form
Hello I have a 3x3 matrix (A), which I would have to reduce to Reduced Row echelon form.  Besides, at every iteration k, the elementary row matrix Ek has to be printed and also print the product of sum Ei (i=1 to k) and A. Any ideas how to go about doing this. KS. [[alternative HTML version deleted]]

potencia fracional de un número negativo
Mirando los comentarios, realmente lo que deseo es encontrar la raíz real de (-0.5)^(1/5) la cual debería ser -0.87055056329. José me hace caer en cuenta que además de no encontrar la raiz real, tampoco da todas las raiz complejas. Habría alguna manera de que tuviera en cuenta? > ------------------------------ > > Message: 6 > Date: Thu, 15 Oct 2015 11:25:39 +0200 > From: José

potencia fracional de un número negativo
El problema del módulo es que pierde el signo. En tu caso sale igual porque has invertido el signo del coeficiente en el polinomio (en realidad se me pasó a a mí advertir que el término independiente debe ir con signo negativo): .> polyroot(z=c(0.5,0,0,0,0,1)) [1] 0.7042902+0.5116968i -0.2690149+0.8279428i -0.2690149-0.8279428i [4] 0.7042902-0.5116968i -0.8705506+0.0000000i .> .>

upgrading storage on hardware RAID 10 possible?
Hi all, Can anyone please tell me, from experience, if it's possible to upgrade the hard drives in a RAID 10 system from 250GB HDD's to 500GB / 750GB HDD's, while the server is running? The server runs CentOS 5.5 x64. Our hardware vendors simply always say no, so we never actually tried doing this, and when a client needed an upgrade like this we had to build a new server with the

Memory scope proposal
Hi all, Currently, the LLVM IR uses a binary value (SingleThread/CrossThread) to represent synchronization scope on atomic instructions. We would like to enhance the representation of memory scopes in LLVM IR to allow more values than just the current two. The intention of this email is to invite comments on our proposal. There are some discussion before and it can be found here:

Problems booting 2.6.7 Dom0 with 3ware Controllers
I tried to install and boot a 2.6.7 Dom0 xenLinux Kernel on an SMP (Dual-Xeon) Machine with 2 3-ware Controllers installed (1 4-channel Controler and 1 8-channel Controler, both Parallel ATA) and no other HDs present (except the ones connected to the 3ware controlers, of course). First of all I got a compilation error after activating the SMP option in the kernel config. After deactivating the

Memory scope proposal
Ke, I'll be the bearer of bad news here. The radio silence this proposal has gotten probably means there is not enough interest in the community in this proposal to see it land. One concern I have with the current proposal is that the optimization value of these scopes is not clear to me. Is it only the backend which is expected to support optimizations over these scopes? Or are you
