Search Results for "root"

...We have outsourced a lot of functionality of PyTorch Geometric to other packages, which needs to be additionally installed. These packages come with their own CPU and GPU kernel implementations based on C++/CUDA extensions. We do not recommend installation as root user on your system python. Please setup an Anaconda/Miniconda environment or create a Docker image. We provide pip wheels for all major OS/PyTorch/CUDA combinations.

Application for polynomial roots calculation. The application does the job by supposing the roots of the derivative function are known. This way, we can delimit the range where each possible root is in, and by applying Bolzano's theorem, we can find the zeroes. It is not a very eficient way, as we must calculate al the derivatives of the polinomial, implying very high numbers (n!), that make the needed precision increase, making the computational complexity for high-degree polinomials poor. But I have been able to make it work with a 40-degree polynomial, with two very proximal zeroes arround x=1000. ...

...Furthermore, these calculations are written entirely in the native MATLAB language, and thus the process may be repeated to obtain nth order derivative files. The package is particularly appealing for applications where the same derivative must be found at multiple different points, i.e. non-linear root finding/optimization, stiff ode integration, etc.

...The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.putVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.putVariable("x", i); }

GiNaCRA is a C++ library providing data structures and algorithms for Real Algebraic computations. GiNaCRA is based on the efficient C++ library GiNaC including support for symbolic manipulations on polynomials.

IMPORTANT: This project have been migrated to GitHub (https://github.com/krvajalmiguelangel/libnumerica) To use this or leave feedback, please visit github site instead. numerica implements some of the basic numerical algorithms about root-finding, interpolation, system of linear equations, integration, and ordinary differential equations. The aim is to be simple, code-readable and generic. New features of the recently approved c++11 are used.

MESH is a tool that measures distortion between two discrete surfaces (triangular meshes) using the Hausdorff distance to compute a maximum, mean and root-mean-square errors between two given surfaces. It also displays the error values on the surface.

Numerical math is tool that demonstrates numerical math methods. It includes following areas: interpolation, numerical differentiation, numerical integration, root finding, linear systems, non-linear systems, differential equations.
