基于MATLAB的遗传算法源程序，大家可以共同讨论这个。(based on MATLAB source of the genetic algorithm, we can discuss this.)

说明：  捷联惯导系统导航解算. 根据600秒的指北方位捷联系统的数据进行导航解算，飞行高度不变，采样周期0.01s.(Strapdown inertial navigation system navigation solution. Based on the 600 seconds that the north-bit data SINS navigation solution, the same altitude, sampling period 0.01s.)

3.不对称的随机极性甚小幅相调制系统.rar(3.Very slightly asymmetric random polar phase modulation system.rar)

qpsk的调制解调源码，注释详细。功能正常。很适合学习调制解调的人.文件包含： qpsk_mod_demod.m(qpsk mod and demod procedure qpsk_mod_demod.m)

梯度下降法工具箱，包括了L_BFGS等。MATLAB版(gradient descent toolbox, including L_BFGS, MATLAB edition)

这次使用的设计软件是MATLAB的GUI模块，要设计一个音乐键盘要知道一个最简单的键盘本身要有36个发音键，既21个音阶和15个辅音阶。(The use of MATLAB software is the design of the GUI module, to design a music keyboard to know one of the most simple keyboard itself will have 36 pronunciation key, already 21 scales and 15 auxiliary scales. )

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)
