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
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.
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

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
What you are looking for is ng-cloak. You have to add it like this: <body class=”{{ bodyClass }}” ng-cloak> and this will prevent unwanted flashing. Link to docs about this. Edit: It is also advisable to put the snippet below into your CSS file, according to docs. “For the best result, the angular.js script must … Read more
If you are enlarging the image, you should prefer to use INTER_LINEAR or INTER_CUBIC interpolation. If you are shrinking the image, you should prefer to use INTER_AREA interpolation. Cubic interpolation is computationally more complex, and hence slower than linear interpolation. However, the quality of the resulting image will be higher.
An easy solution, as you mentioned, is to simply connect the points with a straight line. Here’s the code to do so: public void onDraw(Canvas canvas) { Path path = new Path(); boolean first = true; for(Point point : points){ if(first){ first = false; path.moveTo(point.x, point.y); } else{ path.lineTo(point.x, point.y); } } canvas.drawPath(path, paint); } … Read more
Lets define first a simple helper function in order to make it more straightforward to handle indices and logical indices of NaNs: import numpy as np def nan_helper(y): “””Helper to handle indices and logical indices of NaNs. Input: – y, 1d numpy array with possible NaNs Output: – nans, logical indices of NaNs – index, … Read more
Cause Some images are just very hard to down-sample and interpolate such as this one with curves when you want to go from a large size to a small. Browsers appear to typically use bi-linear (2×2 sampling) interpolation with the canvas element rather than bi-cubic (4×4 sampling) for (likely) performance reasons. If the step is … Read more
