多种群遗传算法打代码，下载自行查阅，是30个遗传算法案例的第7个案例(Multi-population Genetic Algorithm code EliteInduvidual.m、immigrant.m、MPGA.m、SGA.m、ympga.m、ympgaMain.m、ysga.m、ysgaMain.m Multi-population Genetic Algorithm code EliteInduvidual.m、immigrant.m、MPGA.m、SGA.m、ympga.m、ympgaMain.m、ysga.m、ysgaMain.m Multi-population Genetic Algorithm code EliteInduvidual.m、immigrant.m、MPGA.m、SGA.m、ympga.m、ympgaMain.m、ysga.m、ysgaMain.m)

优化问题求解方法包括牛顿法、共轭梯度法和最速下降法(The optimization problems are solved by Newton method, conjugate gradient method and steepest descent method)

matlab编写的正态云发生器与云拟合程序，其中有较详细的注释。(matlab prepared in the normal cloud generator and cloud fitting procedures, including more detailed notes.)

说明：  logistic regression algorithm in matlab.

it generates the BPSK signal

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)

用镜像矩阵求出矩阵的QR分解（正交三角分解），并求解线性方程组，该方法不必选主元，但其计算过程非常稳定。也可用于求矩阵的广义逆和求解线性最小二乘问题。子过程QRDCMP用镜像矩阵求m*n矩阵A的QR分解，A=Q^TR,其中Q是m*m正交矩阵，R为m*n上三角矩阵；子过程QRBKSB用矩阵的QR分解求解线性方程组Ax=b，其中A为n阶非奇异方阵。(Matrix obtained with the mirror matrix QR decomposition (orthogonal triangular decomposition), and solving linear equations, the method does not have to choose the main element, but its calculation process is very stable. Can also be used to find the generalized inverse matrix and solving linear least squares problems. Sub-process of the mirror matrix QRDCMP m* n matrix A QR decomposition, A = Q ^ TR, wherein Q is a m* m orthogonal matrix, R is m* n upper triangular matrix subprocess QRBKSB a QR decomposition to solve the matrix linear equations Ax = b, where A is non-singular square matrix of order n.)
