在Matlab中实现了Cordic快速算法，并实现了sin(x), cos(x), atan(y/x), sqrt(x^2+y^2)等函数的快速计算，并附加了误差分析的结果图，代码清晰简洁，对Cordic算法的迭代次数确定，有一定的指导意义(Cordic implemented in Matlab fast algorithm, and realized sin (x), quickly calculate cos (x), atan (y/x), sqrt (x ^ 2+y ^ 2) and other functions, and attach the results of the error analysis Figure, clear concise code, Cordic algorithm for determining the number of iterations, there are certain guiding significance)

这是一个matlab编写的计算人脸识别率的小程序，选用的图像数据库位ORL数据库。(This is a face recognition matlab calculation of the rate of the preparation of small procedures, digital image database selected ORL database.)

matlab s-function for discrete state equation

用矩阵撕裂法，多次用matlab运算，得出复杂系统的15个节点的电压(Tear voltage matrix method, repeatedly using matlab computing, complex systems derived 15 nodes)

matlab例题源代码，包含很多典型的例题，很值得借鉴学习。(Example matlab source code contains many typical Example, it is worth learning to learn.)

采用一种快速收敛变步长LMS（Least mean square ） 自适应最小均方算法matlab源程序，其中算法所做的工作是用FIR 滤波器的预测系统，对IIR系统进行预测，如果阶数越高越能逼近被预测系统。(Using a fast convergence of variable step size LMS (Least mean square) adaptive least mean square algorithm matlab source, one of algorithm is the work done by FIR prediction filter systems, prediction of IIR systems, if the higher order the more it can be prediction system approximation.)
