数字信号处理应用matlab,包含了相关的多个内容，较为经典(Application of digital signal processing matlab, contains a number of related content, the more classic)

该程序为matlab代码。通过对相同数据分别进行DFT与FFT这两种变换，来对比两者的异同。(The program for the matlab code. By the same data were carried out both DFT and FFT transform, to compare the similarities and differences between the two.)

实现十进制负数求二进制的补码，方便广大学者实现视频或图像加解密过程中用到异或加密(Seeking to achieve a negative decimal binary complement, facilitate the realization of the majority of scholars, video or images used in encryption and decryption process XOR encryption)

计算含氧量变化与其他参数直接的函数关系的程序，也可以用于计算其他不同参数与结果的函数关系(Calculation of oxygen content and other parameters of the function of the program directly, it can be used to calculate the different parameters and results of other function)

matlab的资料,PPT的很好用，我用过了(matlab use very good)

自己写的几个matlab的函数，自己处理数据是常用。有滤波函数、平移函数等。处理后新生成的数组和原数组大小相同，行列特性也相同。(Himself wrote several matlab functions, deal with their own data is commonly used. There are filtering function, translation function, and so on. The new array is generated after treatment and the original array the same size, the ranks of features are the same.)

说明：  能够对于奇异值的计算matlab代码，它可以加强攻击性的抵抗能力。(Singular value can be calculated for the matlab code, which can enhance resistance to attack.)

this source code based on steganography and developed in matlab. in steganography we can hide any data like images in another image. this method based on discrite cosine transform method.

The alogrithm employed in this toolbox for determining Lyapunov exponents is according to the algorithms proposed in [1] A. Wolf, J. B. Swift, H. L. Swinney, and J. A. Vastano "Determining Lyapunov Exponents from a Time Series," Physica D, Vol. 16, pp. 285-317, 1985. [2] J. P. Eckmann and D. Ruelle, "Ergodic Theory of Chaos and Strange Attractors," Rev. Mod. Phys., Vol. 57, pp. 617-656, 1 The algorithm given in [1] is used for first-order systems while the QR-based algorithm proposed in [2] is applied for higher order systems. by Steve W. K.
