matlab下数字信号处理实现实例，对初学者很说是很好的教材，包括源码实现(digital signal processing under matlab realize examples, for beginners it is good teaching materials, including source code to achieve)

The book of EM numerical methods

10Multivariate refinement equations and convergence of subdivision schemes HJ97

说明：  1. 编程实现图像傅立叶高通、低通滤波。 2. 尝试傅立叶压缩。 (1. Programming image Fourier high-pass, low pass filtering. 2. Try Fourier compression.)

利用DFT变换实现数字水印的源代码，请大家赐教··(the code about the digital watermark in the region of DFT，using matalab)

说明：  数字信号调制中的ASK,PSK,FSK的matlab仿真程序，包含了调制与解调过程(Digital signal modulation of ASK, PSK, FSK the matlab simulation program, including the modulation and demodulation process)

最小二乘法测向技术研究，很好的文章，大家一起研究一下(Least squares method to measure the technology, very good article, we study together)

Record your voice for 5 seconds Play back the recording Store data in double-precision array Plot the waveform Calculate over all the frames in the sample LPF the speech at 900 Hz to remove upper freq. (since Pitch info. will be below 900 Hz) Perform Centre Clipping and find the Clipping Level (CL) Choose the appropriate clipping level Perform Center clipping Compute the autocorrelation calcute pitch Calculate the avg. pitch estimate for the whole sample X. Find Gender

这6个程序可用于0—9的数字识别，算法包括：基于类中心的欧式距离法、马氏距离法、夹角余弦距离法 、二值化的夹角余弦距离法、二值化的Tanimoto测度法和增量校正算法，均为基于matlab软件编写的程序。学会了这几个算法，可以在这些程序的基础上进行扩展，对三维模型识别算法的编程有一定的帮助。(6 program can be used 0-9 digit recognition, algorithms include: class center Euclidean distance, Mahalanobis distance method, the cosine of the angle distance method, the cosine of the angle distance method binarization, binary of Tanimoto Measure Method and incremental correction algorithms are written based on matlab software program. Learned these algorithms can be extended on the basis of these procedures, programming algorithm of the three-dimensional model to identify some help.)
