I\'m looking for a non-iterative function that finds the real roots开发者_开发百科 of cubic polynomials. So, an implementation of something like this.
I\'ve been using python + numpy for a while, and got familiarized (and char开发者_JS百科med) with it. Now, I need to do some calculations using C++, and was looking for a nice library to do numerical
Lately I have been doing some numerical method programming in C. For the bug fixing and throubleshooting it\'s nice to have some visual representation of what is happening. So far I have been outputti
R can generate a spline function using splinefun() in the splines library. However, I need to evaluate this function at its first and second derivatives. Is there a way to do this?
Suppose you have a general shape defined by a bunch of coordinate points that form something that looks like a circle, ellipse, or general closed curve - how do you find the a开发者_Python百科rea boun
One would expect and hope that if you ask Mathematica to find the roots of a polynomial, it should give the same (approximate) answers whether you do this symbolically, then find numerical approximati
I\'m trying to use numpy.optimize.curve_fit to estimate the frequency and phase of an on/off sequence.
I\'m trying to convert a simple numerical analysis code (trapezium rule numerical integration) into something that will run on my CUDA enabled GPU.There is alot of literature out there but it all seem
Non-standard mathematical analysis extends the开发者_JAVA百科 real number line to include \"hyperreals\" -- infinitesimals and infinite numbers.Is there (specification for an) implementation of a data
