% 141116 **** RIEMANN Developers: Javier Rodríguez-Laguna, Silvia N. Santalla, Tom LaGatta and Rodolfo Cuerno. 1. PURPOSE A program to compute geodesics and balls in 2D Riemannian manifolds. See http://arxiv.org/abs/1407.0209 for a research application of this code. 2. INSTALLATION The program is written in C++ for a UNIX environment with gcc compilers, BLAS & LAPACK. In order to watch all the animations, you need the following libraries, including the development files: * BLAS & LAPACK * X11 For example, in ubuntu, apply the following command: >> sudo apt-get install g++ libblas3 libblas-dev liblapack3 liblapack-dev libx11-dev In other UNIX systems the packages may have different names. Now enter each directory and do: >> make xriemann >> ./xriemann A window should open, and an image like that in example.png should appear.
