interpolation

I've already looked at this , which was helpful to a point. Here's the problem. I have a list of users propagated into an element via user click; something like this: <div id="box"> joe-user page-joe-user someone-else page-someone-else </div> On click, I want to make sure that the user has not already been clicked into the div. So, I'm doing something like: if ( ! $('#box').html().match(rcpt) ) { update_div(); } else { alert(rcpt+' already exists.'); } However, with existing lack of interpolation that javascript has for regular expressions, is causing my alert to trigger in the use-case where

I have data that looks like the following but I also have control of how it is formatted. Basically, I want to use Python with Numpy or Pandas to interpolate the dataset to achieve second by second interpolated data so that it is a much higher resolution. So I want to linearly interpolate and produce new values between each of the real values I currently have while keeping the original values as well. How can I accomplish this with Pandas or Numpy? As an example, I have this type of data: TIME ECI_X ECI_Y ECI_Z 2013-12-07 00:00:00, -7346664.77912, -13323447.6311, 21734849.5263,@ 2013-12-07 00

Code is here: http://jsfiddle.net/S48QX/ . I want to draw a image based on a 3D data set, for example: var data = [ {x:1.428, y:0.500, energy:0.458}, {x:1.428, y:1.191, energy:0.616}, {x:1.428, y:1.882, energy:0.795}, {x:1.428, y:2.573, energy:0.642}, {x:1.428, y:3.264, energy:0.536}, {x:1.428, y:3.955, energy:0.498}, {x:1.428, y:4.646, energy:0.494}, {x:1.428, y:5.337, energy:0.517}, ... } It's like scattered plot, but I need every pixel to be set, not just a bunch of color dots on the image. So, my question is how can I interpolate scattered dots with d3.js. The generated image here is the

This is a continuation of a question that I had originally posted at http://r.789695.n4.nabble.com/subset-between-data-table-list-and-single-data-table-object-tp4673202.html . Matthew had suggested that I post my question here so I am doing that now. This is my input below: library(data.table) library(pracma) # for the interp1 function tempbigdata1 <- data.table(c(14.80, 14.81, 14.82), c(7900, 7920, 7930), c("02437100", "02437100", "02437100")) tempbigdata2 <- data.table(c(9.98, 9.99, 10.00), c(816, 819, 821), c("02446500", "02446500", "02446500")) tempbigdata3 <- data.table(c(75.65, 75.66, 75

I'm in the process of rewriting a coworkers IDL code into python and am coming up with some differences that I'm confused about. According to other SO questions and mailing list threads I've found if you use scipy.ndimage.interpolation.map_coordinates and specify order=1 it is supposed to do bilinear interpolation. When comparing results between the IDL code (run in GDL) and python (map_coordinates) I got different results. Then I tried using mpl_toolkits.basemap.interp and I got the same result as the IDL code. Below is a simple example that shows what is wrong. Could someone help me figure

I'm using opencv remap function to map an image to another coordinate system. However, my initial tests indicate that there are some issues with the interpolation. Here, I give a simple example of a constant 0.1 pixel shift for a image that is 0 everywhere but at position [50,50]. import cv2 import numpy as np prvs = np.zeros((100,80), dtype=np.float32) prvs[50:51, 50:51] = 1. grid_x, grid_y = np.meshgrid(np.arange(prvs.shape[1]), np.arange(prvs.shape[0])) grid_y = grid_y.astype(np.float32) grid_x = grid_x.astype(np.float32) + 0.1 prvs_remapped = cv2.remap(prvs, grid_x, grid_y, interpolation

I have a set of two animations, both animations run together using the overshoot interpolator <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/overshoot_interpolator" > <translate android:duration="6000" android:fromXDelta="100%" android:toXDelta="0%" /> <scale android:duration="6000" android:fromXScale="1.0" android:toXScale="0.6" android:pivotX="0" android:fromYScale="1.0" android:toYScale="1.0" android:repeatCount="1" android:repeatMode="reverse" /> </set> I want the translate animation to overshoot,
