romanwsgit / cppfortraninterop

This project aims to call Fortran functions and subroutines from C++ and compares them with the functionality available in the C++ ecosystem.

CppFortranInterop

CppFortranInterop is a project focused on interoperability between C++ and Fortran. It provides a C++ interface for eigenvalue decomposition using a Fortran routine from the LAPACK library. The project takes advantage of the Eigen library and is configured to work on an M1 Mac using Accelerate.

Prerequisites

• A modern C++ compiler supporting the C++17 standard
• A Fortran compiler
• Eigen library installed and configured correctly
• LAPACK library, preferably the version included with the Accelerate framework for optimal performance on M1 Macs

Installation

1. Clone the repository: git clone https://github.com/yourusername/CppFortranInterop.git

2. Navigate to the cloned directory: cd CppFortranInterop

3. Review the Makefile to ensure Eigen paths and other related variables are correctly set.

4. Build the project using the Makefile: make

Usage

This project is meant as a backend to perform efficient eigen decomposition using Fortran routines. You can include the header files in your source file. There is an example usage in the main.cpp file.

Contributing

Contributions are welcomed. Please open an issue first to discuss the changes you wish to make.
