Hi all, I'm attempting to convert all the pointers to arrays the mdct_backward function so it can be partitioned off for a hardware implementation. Although this code is quite short I'm finding it a little tricky. As it stands, mdct_backward is passed values by reference i.e. void mdct_backward(mdct_lookup *init, DATA_TYPE *in, DATA_TYPE *out) o my modified version starts void

With this set-up options(warn = 1) tf <- tempfile() finalizer <- function(obj) { message("finalizer") close(obj$f) } this code works ev <- new.env() ev$f <- file(tf, "w") reg.finalizer(ev, finalizer) rm(ev) gc() whereas this (reversing the order of file() and reg.finalizer()) ev <- new.env() reg.finalizer(ev, finalizer) ev$f <- file(tf,

Hi, I'm working on a project to generate native code for a domain specific langauge where the user defines functions in the complex plane. This implies that I need to support complex numbers as a datatype with LLVM. Its fairly straightforward to create a struct of two floats (or doubles, etc.) and do the simple operations like add, subtract, multiply, divide, etc. However, things get

As some of you know, I'm creating a hardware MDCT core. At the moment I'm working out the best way to create a lookup table for the trig values, as set up in mdct_init: /* trig lookups... */ for(i=0;i<n/4;i++){ T[i*2]=FLOAT_CONV(cos((M_PI/n)*(4*i))); T[i*2+1]=FLOAT_CONV(-sin((M_PI/n)*(4*i))); T[n2+i*2]=FLOAT_CONV(cos((M_PI/(2*n))*(2*i+1)));

i'd like to know if there is any plan or existing work to add a Aho's trig language like code generator generator? "...If you are starting a new port, we recommend that you write the instruction selector using the SelectionDAG infrastructure." any other things i should know before i write one? thank you.

Hi We have a mystical error occurring in a special case. When we run a citrix client on the Windows client we will not receive any printouts - no printer dialogue box are opened either. From windows we get nothing - no message box no nothing. * We are running SAMBA 2.2.6 on solaris 7 * We are running a citrix client on Windows 2000 Pro SP3 connected to the SAMBA without domain.

We are slowly making the code generators more and more automatically generated as time goes on. The SelectionDAG infrastructure is mean to support exactly this (perform Tree or DAG pattern matching on the optimized DAG

Hello All, I cant seem to do a trig regression in R. The equation is as follows : y = a+b*(sin((2*pi*x/360) - c))^2 a, b, c are coefs that I want. y, x are input vectors. The equation I put into R: lm(y ~ sin(2*pi*x/360)^2) This equation is missing the c and I dont get the right answer. Also, I dont know how to plot the lm over the x values instead of the indices. Any help is sincerely

Hi, Dirk Eddelbuettel advised me to write here. Here is my original letter to him: I would like to enquire about package r-cran-rjava on Debian jesse. It seems that if default-jre package is not installed, but openjdk-7-jre is installed, then library(rJava) in R fails. I?ve been bitten by this today and I wonder whether this an issue of mine, or is this a possible bug. My server admin used

When loading a package with library(APkg) or require(APkg) I would like to make sure that (1) the correct version of [R] is installed. If not an informative error message should be given. I would also like to make sure that (2) another required package which is loaded from within the APkg package (by require(OtherPkg)) is of a certain version or later. First of all, I believe that the check

Hello, I've checked the FAQ and followed steps I can find there. I made sure my /etc/hosts is correct as in the FAQ. I tried complete uninstall/reinstall of Wine and data. Iceweasel and all other normal linux programs work fine to resolve addresses. WoW under Wine works fine. Fresh install of Firefox for Windows only works under Wine if I use a IP address instead of a hostname, so Wine

I am surprised by this. Why does R not do this automatically? What is the case for keeping the DLL loaded after the package has been unloaded? What
