Would it be wrong to generate the llvm.assume IR suggested below? in GVN? Given more info via the AssumptionCache, InstCombine can then do more optimizing.

Thanks for the response. Yes, I did study the vignette but did not understand it fully. Anyway, I have tried once again now. I am happy to say that I have got what I wanted. library(Ryacas) x <- Sym("x");U <- Sym("U");x0 <- Sym("x0");C <- Sym("C") my_func <- function(x,U,x0,C) { return (U/(1+exp(-(x-x0)/C)))} FirstDeriv <-

Hi all, I am trying to implement the following matlab code with Ryacas : syms U x x0 C d1=diff(U/(1+exp(-(x-x0)/C)),x); pretty(d1) d2=diff(U/(1+exp(-(x-x0)/C)),x,2); pretty(d2) solx2 = solve(d2 == 0, x, 'Real', true) pretty(solx2) slope2=subs(d1,solx2) I have tried the following : library(Ryacas) x <- Sym("x");U <- Sym("U");x0 <-

Dear all, I would like to draw a dendrogram and mark some parts/branches (by using "segments") including their labels. If I draw it without specifying the length of x axix, I am able to do that (as in My dendrogram 1 of the following codes). However, if I want to specify the x axix, I am not able to draw marking line (by using "segments") including labels (as in My dendrogram

Me encantaría saber pensar así de una. Creo que entiendo bien lo que me decís, pero no lo puedo poner en marcha en mi computadora, por algo que no sé qué será.

Have you studied the "Introduction to Ryacas" vignette that come with the package?

I found a form of the if statement that works but it is very long.

I am using gam in mgcv (1.3-22) and trying to use gcv to help with model selection. However, I'm a little confused by the process of assessing GCV scores based on their magnitude (or on relative changes in magnitude). Differences in GCV scores often seem "obvious" with my poisson gams but with negative binomial, the decision seems less clear. My data represent a similar pattern as

Thanks for prompt response, Andy This will work for cases when address is not modified. However this doesn’t seem to work for pre/post increment load stores. Consider data to address forwarding: $x0 = ldr x0, [x1] $x0, $x2 = ldr x2, [x0, 16]! The second instruction will have it’s own latency for address modification ($x0 register). So I don’t see how we can use ReadAdr stuff here. May be

Hi all, I would like to get the array index for a range of values, say 0 < x < 1.5. I'm wondering if there is an alternative for the following which I've done x0 <- rnorm(100) x1 <- ifelse(x0 > 0 & x0 < 1.5,"t","f") x2 <- which(x1=="t",arr.ind=TRUE) x0[x2] Thanks. -- Muhammad

Thank you in advance. Now I want to make comparison of the different bandwidth h in a normal distribution graph. This is the table of bandwidth h: thumb rule (normal)--0.00205; thumb rule(Epanech.)--0.00452; Plug-in (normal)--0.0009; Plug-in(Epanech.)--0.002. this is the condition: N=1010 data sample is from normal distribution N(0,0.0077^2). The grid points are taken to be [-0.05,0.05] and

Hi list, Is it possible to simulate load to store forwarding on aarch64 with MI scheduling model on AArch64? For instance $x0 data latency in the example below should be 1 cycle ldr $x0, [$x1] str $x0, [$x2] But it should be 4 cycles if we have another instruction: ldr $x0, [$x1] add $x0, $x0, 4 For ALU instructions it’s possible to use either ReadAdvance or SchedReadAdvance, but I don’t see

Hello dear members of R-help and R-core mailing list, I am not sure if this request is a "ticket" that should be filled somewhere outside the mailing list. If so, I apologize for not doing and would like to know where I should have filled it. And to the subject matter: I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2),
