I am trying to do a simple quadratic function that would return number of roots and their values via an enum: enum QuadraticResult { None, OneRoot(f32), TwoRoots(f32, f32), } fn solveQuadratic...

CLPFD-systems are not primarily targeted to handle quadratic equations efficiently, nevertheless, are there better ways to formulate problems like the following? It seems the problem boils down to...

I have three points in 2D and I want to draw a quadratic Bézier curve passing through them. How do I calculate the middle control point (x1 and y1 as in quadTo)? I know linear algebra from college ...

I was doing a program to compare the average and maximum accesses required for linear probing, quadratic probing and separate chaining in hash table. I had done the element insertion part for 3 ca...

I'd like to calculate a point on a quadratic curve. To use it with the canvas element of HTML5. When I use the quadraticCurveTo() function in JavaScript, I have a source point, a target point and ...

I'm looking for an approach to splitting a four sided shape into a grid. For example: Ultimately I need to be able to convert the resulting shapes to SVG, but I'm happy to handle conversion to/fr...

This is my sample data. I want to plot both y1 and y2 against x1 in a single plot. This is what I did: library(ISLR) library(ggplot2) y1<-scale(Auto$horsepower,scale = T,center=T) y2<-scale...

I was reading the Go programming language book (by Donovan and Kernighan) and about their example echo1, they said: "This is a quadratic process that could be costly if the number of arguments is l...

I have the following linear regression: import statsmodels.formula.api as sm model = sm.ols(formula = 'a ~ b + c', data = data).fit() I want to add a quadratic term for b in this model. Is there ...

I have a quadratic curve drawn on html canvas using context.quadraticCurveTo(controlX, controlY, endX, endY); . I have the control-point and the starting and end points, which are not necessarily ...

Here's an interesting puzzle. Below is an R snippet that identifies the tangency point of a quadratic function with respect to a line drawn from the point (0,rf) on the y-axis. For those famili...

I've implemented marching cubes, dual marching cubes and adaptive marching cubes in C#, only to find out that I need dual contouring for my purposes. I've read all works about dual contouring and I...

I am trying to use solve.QP to solve a portfolio optimization problem (quadratic problem) Total 3 assets There are 4 constraints: sum of weights equal to 1 portfolio expected return equals to 5...

The only Google search result I found is QuadProg++ but it can not solve the quadratic programming problem whose matrix is not applicable for Cholesky decomposition. So can anyone give me so...

I have to write a read method for a quadratic class where a quadratic is entered in the form ax^2 + bx + c. The description for the class is this: Add a read method that asks the user for an equat...

I am trying to write a function in C++ that solves for X using the quadratic equation. This is what I have written initially, which seems to work as long as there are no complex numbers for an answ...

I have a question regarding formula curving through a control point. As you know, HTML Canvas has quadraticCurveTo(x1, y1, x2, y2) with x1 and x2 being the control point. However when you try to d...

I'm looking for a good easy to use Java based Quadratic Programming (QP) solver. Googling around I came across ojAlgo (http://ojalgo.org). However, I was wondering if there are any other/...

I currently have a class called Polynomial, The initialization looks like this: def __init__(self, *termpairs): self.termdict = dict(termpairs) I'm creating a polynomial by making the keys the...

I have two independent variables, GSH and Gls. Using these two variables, I'm trying to predict an outcome, prob. Using a function of the form: prob=a*Gls^2+b*GSH^2+c*Gls+d*GSH+e // (where a,b,c,d...
