interpolate 3D volume with numpy and or scipy
In scipy 0.14 or later, there is a new function scipy.interpolate.RegularGridInterpolator which closely resembles interp3. The MATLAB command Vi = interp3(x,y,z,V,xi,yi,zi) would translate to something like: from numpy import array from scipy.interpolate import RegularGridInterpolator as rgi my_interpolating_function = rgi((x,y,z), V) Vi = my_interpolating_function(array([xi,yi,zi]).T) Here is a full example demonstrating both; it will help you understand … Read more
How do I make angular.js reevaluate / recompile inner html?
You have to $compile your inner html like .directive(‘autotranslate’, function($interpolate, $compile) { return function(scope, element, attr) { var html = element.html(); debugger; html = html.replace(/\[\[(\w+)\]\]/g, function(_, text) { return ‘<span translate=”‘ + text + ‘”></span>’; }); element.html(html); $compile(element.contents())(scope); //<—- recompilation } })
How to scale images on a html5 canvas with better interpolation?
You need to “step down” several times. Instead of scaling from a very large image to a very small, you need to re-scale it to intermediary sizes. Consider an image you want to draw at 1/6 scale. You could do this: var w = 1280; var h = 853; ctx.drawImage(img, 0, 0, w/6, h/6); Or … Read more
Fish shell – How to interpolate a subcommand?
echo a(echo b)c If you have quotes, you must exit them: echo “a”(echo b)”c” If your subcommand may have newlines, as of fish 2.3, you have to save and restore $IFS: set -l IFS echo “a”(cat ~/file.txt)”c” set -e IFS Eventually string will be able to handle this case.
How to implement linear interpolation?
import scipy.interpolate y_interp = scipy.interpolate.interp1d(x, y) print y_interp(5.0) scipy.interpolate.interp1d does linear interpolation by and can be customized to handle error conditions.
Property binding vs attribute interpolation
Property binding like [trueValue]=”…” evaluates the expression “…” and assigns the value “true” evaluates to the value true “Y” is unknown. There is no internal Y value in TypeScript and no property in the component class instance, which is the scope of template binding. In this case you would want [trueValue]=”‘Y'” Note the additional quotes … Read more
AngularJS multiple expressions concatenating in interpolation with a URL
An alternative to @tasseKATT’s answer (which doesn’t require a controller function) is to use string concatenation directly in the expression a filter: angular.module(‘myApp’) .filter(‘youtubeEmbedUrl’, function ($sce) { return function(videoId) { return $sce.trustAsResourceUrl(‘http://www.youtube.com/embed/’ + videoId); }; }); <div ng-src=”https://stackoverflow.com/questions/23405162/{{ video.id.videoId” youtubeEmbedUrl }}”></div> I’ve found this particularly useful when using SVG icon sprites, which requires you to … Read more
Inverse Distance Weighted (IDW) Interpolation with Python

Floating point linear interpolation
As Jason C points out in the comments, the version you posted is most likely the best choice, due to its superior precision near the edge cases: float lerp(float a, float b, float f) { return a * (1.0 – f) + (b * f); } If we disregard from precision for a while, we … Read more
