LFM

这是一个无线接收机中的维特比译码程序，可供接收设计的朋友参考(This is a decoding program.)

附件是多元回归的参数检验的matlab程序。(the file is the matlab program of parameter test)

基本的拉格朗日乘子法(又称为拉格朗日乘数法)，就是求函数f(x1,x2,...)在g(x1,x2,...)=0的约束条件下的极值的方法。其主要思想是引入一个新的参数λ（即拉格朗日乘子），将约束条件函数与原函数联系到一起，使能配成与变量数量相等的等式方程，从而求出得到原函数极值的各个变量的解。 (Basic Lagrange multipliers (also known as Lagrange multiplier method), is of a function f (x1, x2 ,...) in g (x1, x2 ,...)= 0 constraints under the conditions of extreme value methods. The main idea is to introduce a new parameter λ (the Lagrange multiplier), the constraint function is linked together with the original function, so variables can be paired with an equal number of equations equation, thus obtained by the original function extreme solution of the various variables.)

模式识别中的一部分，用于确定图形边界的算法，不错哦(Part of a pattern recognition algorithm for binary boundary determined )

基于GSF方法的潮流计算，MATLAB程序，故障预算，case30(GSF method based on flow calculation, MATLAB programs, fault the budget, case30)

本文件是用matlab编写的俄罗斯方块，还挺好玩的哦(This document is written using matlab Tetris kinda fun!)

一个基本的小波去噪程序，可以较好的进行语音信号的噪声去除。(A basic wavelet denoising program, we can better for voice signal noise removal.)

增加了遗忘因子的最小二乘递推算法，算法更加准确(The least squares recursive algorithm of forgetting factor is added, and the algorithm is more accurate)

用粒子群算法进行无功优化，比较实用，希望对大家有帮助，14节点的，(Particle swarm algorithm with reactive power optimization, more practical, we want to help, 14 nodes,)

使用蒙特卡罗方法计算n维球体的体积，很有趣的程序(An interesting program for calculating the volume of n-dimensional spheres by Monte Carlo method)
