#+TITLE: CXXBLAS

#+AUTHOR: Stefanos Carlström

#+EMAIL: [email protected]

* Introduction

  C++ (header-only) templated wrappers around CBLAS/LAPACKE.

  

  Tested with OpenBLAS on Linux and Accelerate on macOS.

* Example usage

  scale.cpp:

  #+BEGIN_SRC C++

    #include "cxxblas.h"

    #include 

    #include 

    #include 

    template

    void pvec(const std::vector& v)

    {

      std::cout << "[";

      for(const auto &e : v)

        std::cout << e << " ";

      std::cout << "]" << std::endl;

    }

    int main(int argc, char* argv[])

    {

      int n = 10;

      std::vector> x(n, {0.0, 1.0});

      pvec(x);

      cxxblas::scale(5.0, x);

  

      pvec(x);

      return 0;

    }

  #+END_SRC

  CMakeLists.txt:

  #+BEGIN_SRC cmake

    cmake_minimum_required(VERSION 3.6)

    project(meff)

    # Or wherever cxxblas cmake directory is to be found

    set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cxxblas/cmake")

    include(CXXBLAS)

    add_executable(scale scale.cpp)

    target_link_libraries(scale ${CXXBLAS_LIBRARIES})

  #+END_SRC

  Output:

  #+BEGIN_EXAMPLE

    [(0,1) (0,1) (0,1) (0,1) (0,1) (0,1) (0,1) (0,1) (0,1) (0,1) ]

    [(0,5) (0,5) (0,5) (0,5) (0,5) (0,5) (0,5) (0,5) (0,5) (0,5) ]
