projection_simplex: project an n-dim vector y to the simplex Dn

In RSSL: Implementations of Semi-Supervised Learning Approaches for Classification

project an n-dim vector y to the simplex Dn

Description

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

Usage

projection_simplex(y)

Arguments

y	matrix with vectors to be projected onto the simplex

Value

projection of y onto the simplex
