  "Description": "We provide a number of algorithms to estimate fundamental\nstatistics including Fréchet mean and geometric median for\nmanifold-valued data. Also, C++ header files are contained that\nimplement elementary operations on manifolds such as Sphere,\nGrassmann, and others. See Bhattacharya and Bhattacharya (2012)\n<doi:10.1017/CBO9781139094764> if you are interested in\nstatistics on manifolds, and Absil et al (2007,\nISBN:9780691132983) on computational aspects of optimization on\nmatrix manifolds.",
