HI developers, I want to add trigonometric instructions in my instrinfo.td files how can i directly map these instructions in .td files. Please help me Guys.For Sin, Cos, Tan and Cot Instructions. If I used llvm.sin.* as SDNode Then it is error as llvm variable is not defined SO please Help me. Thanks and Regards Varun -------------- next part -------------- An HTML attachment was scrubbed...

Suppose I do a trigonometric regression fit<-lm(y~ cf + sf) where cf and sf are the cos and sine components. b<-coef(fit) I have the fitted sine component b[2] and the cos component b[3]. Doing summary(fit) gives me the p-values and SEs for b[2] and b[3]. But I want the amplitude of the fitted waveform amp<-sqrt(b[2]^2+b[3]^2) Can someone please tell me how to get the p-value for amp?

https://reviews.llvm.org/D41659 Implemented missing trigonometric optimization in llvm. Here we have implemented the following missing trigonometric optimizations. 1. tan(x)*cos(x)=sin(x) 2. sin(x)*cos(x) = sin(2*x)/2 3. sin(x)/tan(x)=cos(x); 4. tan(x)/sin(x)=1/cos(x); -------------- next part -------------- An HTML attachment was scrubbed...

Good day: I am trying to use readcsvIts("nwr_data_qc.txt",informat=its.format("%Y%m%d%h%M %Y"),header=TRUE,sep="",skip=0,row.names=NULL,as.is=TRUE,dec=".") to read in a file (nwr_data_qc.txt) that looks like this: Time Y M D H Min CO2 2000.18790 2000. 3. 9. 18. 30. 373.60 2000.20156 2000. 3. 14. 18. 30. 373.34

Hola! I have some problems with gam in mgcv. Firts a detail: it would be nice igf gam would accept an na.action argument, but that not the main point. I want to have a smooth term for time over a year, the same pattern repeating in succesive years. It would be natural then to impose the condition s(0)=s(12). Is this possible within mgcv? I tried to obtain this with trigonometric terms, aca:

I see there are still some floating point operations left in the codec init(ialization) code. Changing that code to fixed point is not only difficult (due to the trigonometric functions etc) but may also degrade the precision. Here is an idea whereby we can easily precompute (record) all those values on a powerful processor and then use (replay) them on an embedded processor / DSP. The only

Hey there, I want to plot 5 parabola functions, which happen to be f(x) = 0.25x? + 6,47x -32.6 g(x)=0.99x? -6x -195 j(x)= 0.77x? +14x -495 k(x)=0.001x? + 65x -785 l(x) = 0.9x? -2x -636 in the same graph. Sadly I even do not really understand how to plot just one graph... I found this code in the Internet, which plots a cos-function: >x <- seq( -10, 10, length = 1000) >plot(x,

...e is not the final percentage, it can be 90%... or 50%. The service is ok with both numbers. Although I've solved the problem calculating the slope and making an axis change, I'd like to make something "statistically" stronger, because in the end what I'm doing is making some trigonometrics. If you think on other solutions i'd appreciate your help. Thanks, J.

Dear list: I encountered some problems using the function point.in.polygon() of the sp package, when trying to determine whether some points lye inside, outside, on the border or on a vertice of a polygon. I have a list of point I know should lye right on the border of a polygon, but some of them are not classified as such by point.in.polygon() (see the example code below). To make a long story

I just had a manuscript returned with the biggest problem being the analysis. Instead of using principal components in a regression I've been asked to analyze a few variables separately. So that's what I'm doing. I pulled a feather from young birds and we quantified certain aspects of the color of those feathers. Since I often have more than one sample from a nest, I thought I

Dear LLVM contributors, I am Naoki Shibata, an associate professor at Nara Institute of Science and Technology. I and Hal Finkel would like to jointly propose to add my vectorized math library to LLVM. The library has been available as public domain software for years, I am going to double-license the library if necessary. ******** Below is a proposal to add my vectorized math library,

Dear useRs, Please find the new package mFilter version 0.1-2 on CRAN. The package implements several time series filters useful for smoothing and extracting trend and cyclical components of a time series. The routines are commonly used in economics and finance, however they should also be interest to other areas. Currently, Christiano-Fitzgerald, Baxter-King, Hodrick-Prescott, Butterworth, and

Hi Ganesh, Please have a look at: These core parts of LLVM: http://llvm.org/docs/doxygen/html/classllvm_1_1Loop.html#a72bbf45d2e00971f56bf8cfe4e1df01c http://llvm.org/docs/Vectorizers.html These research projects based on LLVM: http://polly.llvm.org http://aesop.ece.umd.edu I'm not sure what you mean by "identify intrinsic functions". If you really mean LLVM intrinsics,

Hi, For one of our research projects, we are planning to use LLVM. We need the following features: 1. We need to aggressively fuse loops that have inter-loop dependencies. 2. We need to identify intrinsic functions and induction variables. 3. We need to detect few memory access patterns like copy, transpose-copy, stride-copy etc. 4. Lastly, auto-vectorization and

Hi everyone, I am trying to fit a sine function on one year of wind data. I have two questions below. Looking around on the net I managed to get the following: Sine Equation: y = a + b * sin( c + d*x ) b is the amplitude, c is the phase shift, d is something deal with periodicty of data*.* This can be linearised by sin( c+dx ) = cos(c) * sin(dx) + sin(c) * cos(dx). If one calls dx = x1 y

I write about R every weekday at the Revolutions blog: ?http://blog.revolutionanalytics.com and every month I post a summary of articles from the previous month of particular interest to readers of r-help. In case you missed them, here are some articles related to R from the month of September: The deadline to enter the "R Applications" contest with $20,000 in prizes is October 31:

Hi @ll, compiler-rt implements (for example) the MSVC (really Windows) specific routines compiler-rt/lib/builtins/i386/chkstk.S and compiler-rt/lib/builtins/x86_64/chkstk.S as __chkstk_ms() See <http://msdn.microsoft.com/en-us/library/ms648426.aspx> Is there any special reason why compiler-rt doesn't implement other MSVC specific functions (alias builtins or "compiler

Apologies for the off-topic question; as usual I'm trying to draw upon the unparalleled knowledge and sagacity of the r-help list. Please reply off-list if you can help me out. A collaborator of mine found a formula we need, on sheets which he had photocopied out of a book, some years ago. He cannot remember which book (he's getting to be as senile and forgetful as I am, poor bloke!).
