这是关于turbo码的编译码的仿真程序,并附有仿真图(This is a turbo code codec on the simulation program, together with the simulation of Figure)

计算兄弟数，平时练习题，算法比较笨，欢迎指教(Calculate the number of brothers, usually exercises, algorithm is stupid, please advise)

image operations like shrinking and stretching,quantisation

this code shows the stbc model fluctuation.................................................

说明：  对于非均匀线型阵列，以降低波束方向图峰值旁瓣为目标，在给定阵元数和阵列孔径的约束条件下，利用多种群并行进化遗传算法进行阵元布阵优化。(For non-uniform linear array, in order to reduce the peak side lobe of beam pattern, the multi population parallel evolutionary genetic algorithm is used to optimize the array element arrangement under the constraint of the number of array elements and array aperture.)

一个很有用的计算网络中两节点的距离以及平均路径长度的程序，对网络分析很有用(A very computing network with a two-node distance and the average path length of program and very useful for network analysis )

光伏微网逆变器并网matlab/simulink仿真，仿真效果很好，mppt环节采用扰动跟踪法，锁相环部分使用s-function编译(Solar Micro Inverter Grid matlab/simulink simulation, the simulation results very well, mppt link tracking using perturbation method, phase lock loop section compiled using s-function)

线性规划： CmpSimpleMthd(完整单纯形法) 整数规划(含0-1规划) DividePlane(割平面法) ZeroOneprog(枚举法) 二次规划 QuadLagR(拉格朗日法) ActivedeSet(起作用集法)(Linear Programming: CmpSimpleMthd (complete simplex method) Integer programming (including 0-1 Programming) DividePlane (Cutting Plane Method) ZeroOneprog (enumeration method) Quadratic Programming QuadLagR (Lagrangian) ActivedeSet (work set method))

周期高斯一介导、高斯二介导即高斯脉冲（即UWB信号）的功率谱图像，对应不同的占空比和不同的脉冲形式，随着阶数的增加中心频率右移，频谱也为高斯形式，且随着周期数增多，呈现线谱形式(Cycle Gaussian ordinary derivative, ie the Gaussian two-mediated Gaussian pulse (the UWB signal) of the power spectrum image, corresponding to different pulse duty cycle and a different form, with the increase of the order of the center frequency shifted to the right, the spectrum also Gaussian form, and with the number of cycles increased, showing the form of line spectrum)
