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：  用matlab打开即可，可以绘制功率谱的函数(using Matlab can be opened, the power spectral mapping function)

说明：  利用matlab实现彩色图像的分割。算法主要是利用聚类算法(Use of matlab color image segmentation. Algorithm is the main clustering algorithm)

与理论分析结果相比，小波包分析提取振动信号中的特征频率，最小均方误差等算法的MSE的计算。( Compared with the results of theoretical analysis, Wavelet packet analysis to extract vibration signal characteristic frequency, Minimum mean square error MSE calculation algorithm.)

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

二阶线性切换系统稳定切换律的设计与仿真的源程序 (Second-order switched linear system is stable and the design and simulation of switching law)

Garch模型的最大似然估计计方法，基于MATLAB程序。 (The Garch model the maximum likelihood estimator design methodology, based on the MATLAB program.)

实现IIR算法,matlab中的一个很好的典例，仅供大家参考(realise the IIR calculation)

飞机姿态角控制时，基于四元数和欧拉角的位置坐标转换关系，欧拉角控制法同四元数控制方法间的相互转换。(When the aircraft attitude angle control, based on the quaternion and Euler angle of the coordinates of the conversion relationship between the Euler angle control method and quaternion control method conversion between.)

“License-plate-recognition-01-modified-1.zip”使用Matlab，实现自动车牌分割、矫正、识别。(the code can abtain auto-segmentation,and auto-recognition of license plate.)
