偏最小二乘法PLS广泛应用于很多领域。这个程序包提供了一个函数，使用非线性迭代偏最小二乘法NIPALS算法，实现PLS回归。同时包含NIPALS算法的教程(PLS PLS is widely used in many areas. This package provides a function, use of non-linear iterative partial least squares algorithm NIPALS achieve PLS regression. NIPALS algorithm contains tutorials)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)
