这个也是关于空间谱的matlab 挺好的 可以(This is on the spatial spectrum of matlab can be quite good)

说明：  随机数生成程序，用于作为系统辨识的输入信号，得出相应的输出(Random number generator procedure for system identification as an input signal, the output reached)

该程序初步实现了M序列的生成，并且详细地进行了频域法的系统辨识分析。(The program is the initial realization of the M-sequence generation, and detail the frequency domain method of system identification analysis.)

灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。(Gray theory that the behavior of the system even though the phenomenon is dim, the data is complex, but still it is ordered, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. Meanwhile, the gray theory is to generate the data model, not the original data model, so gray prediction data by generating data gm (1,1) model predicted values ​ ​ obtained result of the inverse process.)

利用拉普拉斯变换的思想，通过对数据进行差分，近似得到拉普拉斯变换后的结果，然后检查正负交换的位置，则此为极值点位置，利用此思想得到极值点的位置。(Using the ideas of Laplace transform of the data by the difference approximation get results Laplace transform, and then check the position of the positive and negative exchange, this is the extreme position, take advantage of this thinking of getting extreme points location.)

好东西gba的..................(dsgdsgvvnj)

说明：  给照片加相框，相框的边界可根据照片的尺寸自动调节，支持灰度和彩色jpg照片。(This code frames images with a beautiful frame. Automatically adjusts the bordering i.e. framing according to the image s dimensions. Works for both colored and gray images. )

说明：  蚁群算法的matlab版，希望对初学者有所帮助(ant colony matlab)

蔡氏电路的仿真程序；chua1.m为主程序文件，chua.m为用到的一个函数文件。运行chua1.m后即可出现多个需要的蔡氏电路仿真图(Simulation of Chua a Circuit)

matlab设计低通，带通，高通滤波器分别滤出信号。(matlab design low pass, band pass, high pass filter to filter out the signal, respectively.)
