similar to: Matrix memory layout R vs. C

Hi the list, Is there a way to give a matrix to a C function, and then to use it as a matrix ? I write a function to print a matrix, but I use it as a vector : 1. void printMatrix(double *mTraj,int *nbCol, int *nbLigne){ 2. int i=0,j=0; 3. for(i=0 ; i < *nbLigne ; i++){ 4. for(j=0 ; j < *nbCol ; j++){ 5. Rprintf(" %f",mTraj[i * *nbCol + j]); 6. } 7.

I think we need to relax the test cases. MSVC usually prints the calling convention, and it's often useful information. Maybe we can make the diagnostic text smaller by using the __thiscall, __cdecl, __stdcall, etc keywords when printing types with LangOpts.MicrosoftExt, but it will require moving the attribute from after the identifier to before, which is exciting.

I was going to argue that MSVC doesn't print them, but then I tried, and you're right - it does :) I'll start relaxing the tests then. > Maybe we can make the

Hello, i am trying to vectorize a simple matrix multiplication in llvm; here is my code; #include <stdio.h> #define N 1000 // This function multiplies A[][] and B[][], and stores // the result in C[][] void multiply(int A[][N], int B[][N], int C[][N]) { int i, j, k; for (i = 0; i < N; i++) { for (j = 0; j < N; j++) { C[i][j] = 0;

Hi, there! I'm having kind this same problem https://stat.ethz.ch/pipermail/r-help/2008-October/178221.html but I want to display another plot of my data, which is a point with two arrows indicating confidence interval, in the same graph that I've just plotted another, but the "add=T" is not functioning, I'm getting the same error Warning messages: 1: In plot.window(...)

AFAICT our current version does not correspond to any version in the Linux history. This commit resynchronised to the state in Linux commit 598bae70c2a8e35c8d39b610cca2b32afcf047af. Differences from upstream: find_cpio_data is __init, printk instead of pr_*. This appears to fix Debian bug #785187. "Appears" because my test box happens to be AMD and the issue is that the (valid) cpio

It doesn't fix that test case, unfortunately.

I've been trying to get my head around using matrices in calls to .C(). As an exercise I wrote some code to calculate the product of two matrices. (Well, it makes it easy to check if one is getting the right answer!) After obtaining some advice from a Certain Very Wise Person at Oxford, (to find out how to deal with array indexing in C functions called from elsewhere) I wrote the following

I have to make a boxplot with Years 2011 and 2012 on the x axis, and percentage of full time students (=1) and part time students (=2) on the y axis. I would really appreciate if someone can help me to build a proper code. Thanks Larissa Data as follow: Year Q1 2011 1 2011 1 2011 1 2011 1 2011 1 2011 1 2011 1 2011 1 2011 1 2011 2 2011 1 2011 1 2011 1 2011 1 2011 1

I have written code to compute multi-indices in R [1] and due to the recursive nature of the computation I need to pass around the *same* matrix object (where each row corresponds to one multi-index). As pass by reference wasn't the default behavior I declared a global matrix (mat) and used the <<- operator to write to the global matrix. So the usage would be to call genMultiIndices(3,2)

Hi I have helped a user with a little patch for ogg123. He uses ogg123 for very big files, often more than an hour (blind books). When he breaks the book and later on want to go back to the same chapter, it is a little troublesome to calculate the seconds. Minutes is much more convenient as it is what is written on the screen. I guess my patch is a little buggy and would like to improve it

For the example code below, int L = M + 10; for (k = 1 ; k <=L; k++) { dummy(); if (k < M) dummy2(); } , we can split the loop into two parts like : for (k = 1 ; k != M; k++) { dummy(); dummy2(); } for (; k <=L; k++) { dummy(); } By splitting the loop, we can remove the conditional block in the loop and indirectly increase vectorization

Actually what I meant in my original loop, that there is a dependency between every two consecutive iterations. So, how the loop vectorizer says 'we can vectorize this loop'? for(int k=20;k<50;k++) dataY[k] = dataY[k-1]; From: Henrique Santos [mailto:henrique.nazare.santos at gmail.com] Sent: Sunday, November 03, 2013 4:28 PM To: Sara Elshobaky Cc: <llvmdev at

Hello fellow CentOS-users, on the net there are lots of Spamassassin related HOWTOs - describing how to create a shell script for Postfix and how to install Spamassassin and start its spamd daemon - step by step. Additionally antivirus setups are described... But I have a strong feeling, that this is unneeded on CentOS 6 - because there are already preconfigured stock packages for postfix and

Hello, What is the fastest way to do this? I has to be done quite a few times. Basically I have sets of 3 numbers (as characters) and sets of 3 dashes and I have to store them in named columns. The order of the sets and the column name they fall under is important. The actual numbers and the pattern/order of the sets should be considered random/unpredictable. Sample data: vec =
