Dn = x : x n-dim, 1 >= x >= 0, sum(x) = 1 R translation of Loog's version of Xiaojing Ye's initial implementation. The algorithm works row-wise
projection_simplex(y)
matrix with vectors to be projected onto the simplex
projection of y onto the simplex
Algorithm is explained as in http://arxiv.org/abs/1101.6081
