matlab用来解一般线性或者非线性方程的方法及应用公式。(matlab used to solve a general linear or nonlinear equations and application of formulas.)

A genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

说明：  计算两个离散变量x和y的条件熵z = H（x | y）。 with Input：两个相同长度的整数向量 有益于学习(Compute conditional entropy z=H(x|y) of two discrete variables x and y. with Input: of two integer vector of the same length good for learning)
