Linear Algebra Coming to Standard C++layers std::linalg builds on the C++ Standard Library std::linalg builds on the long history of the BLAS Detailed example: Cholesky matrix factorization # Motivating example: Updating matrix multiply based on the BLAS Basic Linear Algebra Subroutines • BLAS is a standard Fortran & C library • Standard embraced by industry, labs, & academia • Many system vendors have optimized BLAS • e.g., AMD AMD, ARM, Cray, IBM, Intel, NVIDIA, Xilinx • Can implement std::linalg by calling BLAS • If types permit, else fall back to generic C++ • "Based on": • Same set of algorithms • Same design0 码力 | 46 页 | 2.95 MB | 1 年前3
The Idris Tutorial Version 1.1.1language which aims to generate efficient executable code. It also has a lightweight foreign function interface which allows easy interaction with external C libraries. ## I ntended Audience This tutorial is Version 1.0 http://www.idris-lang.org/ Type :? for help Idris> This gives a ghci style interface which allows evaluation of, as well as type checking of, expressions; theorem proving, compilation; in Rust. To define an interface, we provide a collection of overloadable functions. A simple example is the Show interface, which is defined in the prelude and provides an interface for converting values0 码力 | 223 页 | 1.21 MB | 2 年前3
