integrate

Motivation for the question I'm trying to integrate a function f(x,y,z) over all space. I have tried using scipy.integrate.tplquad & scipy.integrate.nquad for the integration, but both methods return the integral as 0 (when the integral should be finite). This is because, as the volume of integration increases, the region where the integrand is non-zero gets sampled less and less. The integral 'misses' this region of space. However, scipy.integrate.quad does seem to be able to cope with integrals from [-infinity, infinity] by performing a change of variables... Question Is it possible to use

I was doing some integration into a loop using integrate and I come up with an error I can't understand neither get rid of. Here is a MWE I could extract: u_min = 0.06911363 u_max = 1.011011 m = 0.06990648 s = 0.001092265 integrate(f = function(v){pnorm(v, mean = m, sd = s, lower.tail = FALSE)}, u_min, u_max) this returns an error "the integrale is probably divergent" which is obviously false. I tried to modify the parameters a little bit and got this working for example: u_min <- 0.07 u_max <- 1.1 m <- 0.0699 s <- 0.00109 integrate(f = function(v){pnorm(v, mean = m, sd = s, lower.tail = FALSE

I am using integrate function in R to integrate a very peaked function. Say that function is a log-normal density: xs <- seq(0,3,0.00001) fun <- function(xs) dlnorm(xs, meanlog=-1.057822,sdlog=0.001861871) plot(xs,fun(xs),type="l") From the plot, I know that the peak is at around 0.3-0.4. If I integrate this density function over its support (with increased abs.tol and increased subdivisions) the integrate gives me zero, which should not be true. integrate(fun,lower=0,upper=Inf,subdivisions=10000000,abs.tol=1e-100) 0 with absolute error < 0 However, if I restrict the interval to 0.3 and 0.4,

We were working on a design, and for that we created the skeleton of the classes in our main branch. Now, we are starting to code, and for that we got a new branch. So, it would be nice if I can move all the new files in the main branch into the new branch. However, I cannot check them in yet. So, is it possible to integrate the checked out changelist? Thanks. bk1e The Perforce support web site explains how to do this: Perforce Knowledge Base: Branching work in progress . It would be nicer if it was a single step that didn't require running eight different commands. Gareth Rees Since release

I am using KIE Workbench 6.1.0.Final and my Eclipse project where I am trying to execute rules is also 6.1.0 Runtime enabled. I like to know how I can execute/load rules created using Drools Guvnor, from my java application. Before posting this question, I have looked at the following similar questions and tried the given approaches but none of them worked for me. Integrating Drool 6 work bench with Java Application why does loading Drools 6 KIE JAR into code fail? Loading Drools/KIE Workbench artifacts directly from the repository KIE Workbench Integration Responds with 401 I have followed

I am trying to develop an application with PHP. There are two possible ways this application will be developed. The first one is to try to do something like www.picnik.com , image processing directly on the browser. The other is to develop CBIR (content-bases image retrieval) algorithms. So, is it possible to send an image from a PHP script to an OpenCV program? Or even display the image being manipulated in real time? Thanks. Doing a google search for 'php opencv' suggests - yes you can :) This one looks decent. http://www.xarg.org/project/php-facedetect/ (I know it's specific to face
