KIVA 3V的入门介绍

实现了bch编码，基于有限域多项式除法,自己动手写的，大家可以看下(Based on division in galois field，relize the BCH code )

糊涂先生给他的五个朋友写信，他写了五封信，但是当他的朋友收到信后，都告诉他：“你的信寄错了”。那么请你计算一下：出现这种情况的概率有多少？（假设糊涂先生是随机地往信封里装信的），你能不能把所有的情况都列出来呢(Mr. foolish to write him five friends, he wrote five letters, but when his friend received a letter, told him: )

读入红细胞图片，通过中值滤波，开运算算，闭运算，和贴标签等方法获得细胞个数 (Read into the red blood cell picture, opening operation count median filtering, and closing operation, and the labeling methods such as cell number)

有限元热计算的算例，做有限元热分析的朋友比较有用(Finite element calculation of hot example, to do finite element analysis of hot Friend more useful)

共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一(Conjugate gradient method (Conjugate Gradient) is between the steepest descent method and Newton' s method between a method that takes only a first derivative information, but to overcome the slow convergence of the steepest descent method shortcomings, but also avoid the need to store Newton and computing the inverse Hesse matrix and disadvantages, conjugate gradient method is not only to solve large linear equations of the most useful methods, large-scale nonlinear optimization solution is the most efficient algorithms)

F-K域偏移法和相移法偏移程序（C语言）(FK domain migration method and the phase- shift method migration program (C language))

基于二阶锥规划的旁瓣抑制滤波器的设计仿真，其中包括m序列，失配滤波器设计，并且考虑增益处理损失。(Based on SOCP sidelobe suppression filter design simulation, including m-sequence mismatch filter design, and to consider the loss of gain processing.)

基于互相关分析的时延估计算法；基于互相关分析的时延估计算法(cross-correlation analysis for time delay calculation)
