As part of a program I'm writing, I need to solve a cubic equation exactly (rather than using a numerical root finder): a*x**3 + b*x**2 + c*x + d = 0. I'm trying to use the equations from here. ...

I wrote the following code to perform a spline interpolation: import numpy as np import scipy as sp x1 = [1., 0.88, 0.67, 0.50, 0.35, 0.27, 0.18, 0.11, 0.08, 0.04, 0.04, 0.02] y1 = [0., 13.99, 27...

I was using one of the proposed algorithms out there but the results are very bad. I implemented the wiki algorithm in Java (code below). x(0) is points.get(0), y(0) is values[points.get(0)], α ...

I have apache server running on Ubuntu. Client connects and downloads an image. I need to extract RTT estimations for the underlying TCP connection. Is there a way to do this? Maybe something like ...

I need a method that allows me to find the Y-coordinate on a Cubic Bezier Curve, given an x-coordinate. I've come across lots of places telling me to treat it as a cubic function then attempt to f...

Based on the following resources, I have been trying to get resolution independent cubic bezier rendering on the GPU to work: GPU Gems 3 Chapter 25 Curvy Blues Resolution Independent Curve Rende...

Here is the thing. I am trying to use fsolve function in Python to find the root of a cubic function. This cubic function has a parameter, deltaW. What I do is change this parameter deltaW from -5...

I'm having the worst time trying to find a JavaScript code that could allow me to do cubic regressions. Would write it myself, but my understanding of polynomial math is, well, suboptimal. So, her...

I'm implementing cubic bezier curve logic in my one of Android Application. I've implemented cubic bezier curve code on canvas in onDraw of custom view. // Path to draw cubic bezier curve Path cu...

This site solves cubic equations, and has the equations it uses I wrote this function to get the same results but it's not working void cubicFormula(float a, float b, float c, float d, floa...

I need to find good approximations of the points where an undefined function intersect a threshold value. I'm stepping through my space and whenever I find that two subsequent steps are on di...
