哈希函数的matlab代码，此函数不可逆，具有加密功能。(Hash function matlab code, this function is not reversible, with encryption features.)

his code is assume sum up of total correlation of transmitter and receiver.

对harrris算法进行改进，使得伪特征点减少，以及时间效率更佳(Improve harrris algorithm, making false feature points reduce, and better time efficiency)

计算水声传播的Krakel程序，属于简正波的计算程序，计算低频声波传播时较适合(underwater acoustic propagting computing program, belong to Normal Mode program, nice when low frequency.)

用最小二乘法反应雷达得到的图像，得到各种数据特征参数(Reaction of the least square method to obtain the radar image data to obtain various characteristic parameters)

(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at 10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.

MUSIC(Multiple Signal Classification)算法是Schmidt在1979年首先提出的，是早期经典的超分辨率DOA估计方法(即超瑞利限的方法)，属特征结构的子空间方法。(MUSIC (Multiple Signal Classification) algorithm is Schmidt first proposed in 1979, is an early classic super-resolution DOA estimation methods (ie, super-Rayleigh limit of the method), is a characteristic structure of the sub-space method.)

详细描述和matlab在图像处理方面的应用，书中附有代码可供参考。(Detailed descriptions and matlab in image processing applications, the book with the code for reference.)

用DWT实现二维小波变换：对图像进行二维小波分解，显示分解结果，最后重构源图像并显示结果 (Achieved using two-dimensional wavelet transform DWT: two-dimensional wavelet decomposition of the image, showing decomposition results, and finally reconstruct the source image and display the results)
