ndarray - 📈 Multidimensional arrays for JavaScript

Javascript

Modular multidimensional arrays for JavaScript.ndarrays can be transposed, flipped, sheared and sliced in constant time per operation. They are useful for representing images, audio, volume graphics, matrices, strings and much more. They work both in node.js and with browserify.

scikit-cuda - Python interface to GPU-powered libraries

Python

scikit-cuda provides Python interfaces to many of the functions in the CUDA device/runtime, CUBLAS, CUFFT, and CUSOLVER libraries distributed as part of NVIDIA's CUDA Programming Toolkit, as well as interfaces to select functions in the CULA Dense Toolkit. Both low-level wrapper functions similar to their C counterparts and high-level functions comparable to those in NumPy and Scipy are provided. Package documentation is available at http://scikit-cuda.readthedocs.org/. Many of the high-level functions have examples in their docstrings. More illustrations of how to use both the wrappers and high-level functions can be found in the demos/ and tests/ subdirectories.

ndarray-gemm - General matrix multiplication for ndarrays

Javascript

General matrix multiply for ndarrays. This is analogous to the BLAS level 3 routine xGEMM.Note that while this implementation is correct, it is not yet very optimized. If someone wants to take over this project or suggest improvements, patches are welcome.

cholesky-solve - [WIP] This module solves sparse symmetric positive definite linear systems by using the Cholesky decomposition

Javascript

This module solves sparse symmetric positive definite linear systems, by finding the Cholesky decomposition(the LDL^T decomposition, and not the LL^T decomposition), and then doing forward substitution and backward substitution. It is basically a Javascript port of the paper "Algorithm 8xx: a concise sparse Cholesky factorization package". This kind of solver has many applications in digital geometry processing.Decomposes M into the Cholesky decomposition of the form LDL^T. A function is returned that can be used to solve the equation Mx = b, for some given value of b.

add - A cross-browser, numerically stable algorithm that adds floats accurately in Javascript

Javascript

A cross-browser, numerically stable way to add floats in Javascript. Produces a faithful rounding of the sum (the result is an immediate floating-point neighbor of the true value).The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

integrate - Some numerical integrators for ordinary differential equations

Javascript

Want one that's not there? Open an issue, or better yet, a pull request adding it. All of the methods are hand-written in asm.js, so they should be fast. Not that your integration method would ever be your bottleneck anyway, but hey... why not.
