Cuckoo Search metaheuristic algorithm to general optimization problem

lte e-node-b matlab code contain code for generating e-node-b in lte simulation

These codes generate simulation results depicted in the paper titled J. Chen, H. Yin, L. Cottatellucci, and D. Gesbert, "Dual-regularized Feedback and Precoding for D2D Assisted MIMO Systems", IEEE Trans. Wireless Commun., 2017. Author: Junting CHEN Email: juntingc@usc.edu Date: May 20, 2016

Stud. Appl. Math. 118, 153-197 (2007)关于solitons的一篇文章，figure6的编程，主要是运用牛顿迭代法进行数值模拟的。(Stud. Appl. Math. 118, 153-197 (2007) on the solitons in an article, figure6 programming, primarily using Newton' s iterative method of numerical simulation.)

半正定矩阵cholesky方法将其分解为两个上下三角矩阵相乘的形式。matlab自带的函数只能分解正定矩阵。并且给出例子。(Semi-definite matrix cholesky method be decomposed into two upper and lower triangular matrices form. matlab built-in function can only be positive definite matrix decomposition.)

这个是我做的弱磁控制。嗯马达在5nm的时候可以从3000rpm超转速到4000rpm(I do this is weakening control. Ah motor in 5nm time can be from 3000rpm super speed to 4000rpm)
