IMAGE--RESTORATION

A function that calculates radial distance between two given vectors

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

MATLAB实现K均值聚类，自己编的，可用，不用系统函数。(MATLAB realization of K-means clustering, own, use, instead of the system functions.)

MATLAB Coder™ generates standalone C and C++ code from MATLAB ® code. The generated source code is portable and readable. MATLAB Coder supports a subset of core MATLAB language features, including program control constructs, functions, and matrix operations. It can generate MEX functions that let you accelerate computationally intensive portions of MATLAB code and verify the behavior of the generated code.

拟牛顿算法源码，结合了简单的案例，可以帮助读者更好的理解接替过程(Quasi-Newton algorithms)

this is basic matlab explanation. i will upload 5documents.

用稳定边界法整定公式来求P,PI,PID的个参数，其中G是已知被校正系统的开环传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量Gc为校正器传递函数，p为系统开环极点的个数（不计重根个数，即多重根只计一个根）(With the Stable Boundary tuning formula seeking P, PI, PID' s parameters, of which G is known to be corrected and the system of open-loop transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters Gc for the corrector transfer function, p is the number of poles of open-loop system (excluding the number of multiple roots, that is a multiple root only to the root))

说明：  共轭梯度算法，非常经典，大家相互交流，如果大家有更好的资源也上传啊，非常感谢(Conjugate gradient algorithm, very classic, everyone to communicate,)

应用matlab求极值和求根的方法，并配有仿真程序和结果，可以用于数值实验时使用(Application matlab extremum and rooting, and with a simulation program and results can be used for numerical experiments)
