利用平面波法计算二维光子晶体能带结构，三角模型(calculation the band structure of Photonics crystal)

CA交通流模型，嗯，就是这个了。。。不错，应该行吧(CA model)

计算Mel倒谱系数的matlab程序： MELCEPST Calculate the mel cepstrum of a signal C=(S,FS,W,NC,P,N,INC,FL,FH) 使用: c=melcepst(s,fs) ％ calculate mel cepstrum with 12 coefs, 256 sample frames(Mel cepstrum coefficients calculated the matlab procedure: MELCEPST Calculate the mel cepstrum of a signal C = (S, FS, W, NC, P, N, INC, FL, FH) using: c = melcepst (s, fs) calculate mel cepstrum with 12 coefs, 256 sample frames)

rake接收机仿真，Rake接收机是一种能分离多径信号并有效合并多径信号能量的最终接收机。瑞克接收的过程相当于用一个钉耙将各个多径信号“耙”出来，然后加以收集。(rake receiver simulation, Rake receiver is a multipath signals can be separated and the effective integration of multi-path signal energy of the final receiver. Rick received the equivalent of using a rake to process each multipath signal " rake" out, and then collecting them.)

本书详细介绍了数学科学计算在matlab中的方法，对初学者有一定的帮助。(This book details the mathematics of scientific computing methods in matlab, there is some help for beginners.)

胡广书数字信号处理的MATLAB程序，函数按章节号命名(HU Guang-book digital signal processing of the MATLAB program)

自适应多速率编码器标准代码，解码端。可将wav文件编码生成amr格式的文件。这种格式的文件可根据信道质量，自动调节编码速率，故称之为自适应。(adaptive multi-rate encoder standard code, the decoder. Wav documents can be generated amr coding format documents. This format of the document is available according to the channel quality, automatic adjustment coding rate, but it is called adaptive.)

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)
