How to install

Install third-part software

To use our code you should install some third-part software

• CMake www.cmake.org/cmake/resources/software.html
• Boost www.boost.org
• IntelMKL software.intel.com/en-us/articles/intel-mkl/ - implementation of BLAS

Correct CMakeLists.txt file

You should insert path to Boost and BLAS (MKL) sources and libraries in file CMakeLists.txt.

The list of libraries to link (${REQUIRED_BLAS_LIBS}) may differ from the above. You can get the list for your architecture here.

Build project

• create folder "build" in directory with source files
• (for Windows users) run "make_project.bat"
• (for Unix users) do next steps

  cd build
  cmake ..
  

These operations create Solution for VisualStudio (Windows) or makefile (Unix). Then you can build the project.
