数学建模算法与应用

说明：  嵌入式系统实验报告 本实验主要是熟悉在非操作系统下，对ARM的硬件资源的使用方法。(Embedded systems laboratory report is familiar with this experiment in non-operating system on ARM hardware resources are used.)

this program calculates the histogram of an inage

一款利用matlab编写的射线追踪程序，易改易用。(The installation of TTBOX is relatively simple. All you have to do is to create some directories and tell MatLab, where TTBOX is. if it does not already exist, create a directory matlab within your home directory. Copy the TTBOX directory into the matlab directory if it does not already exist, create a file startup.m within the matlab directory Insert the following lines into startup.m: basepath= This should be the path to your home directory! addpath([basepath filesep matlab filesep ttbox ],1) addpath([basepath filesep matlab filesep ttbox filesep support ],1) execute startup within the MatLab command window. MatLab is now ready to execute TTBOX routines. The startup-script will be executed automatically upon start of MatLab. In order to read the online documentation, you have to browse to the doc directory and open the ttbox/doc/ttbox.html file with your web browser (it is recommended to set a bookma)

高斯金字塔 优化的版本，可用，效率比较高(Optimized version of the Gaussian pyramid, available, more efficient)

录制汉语拼音 a1（阴平）的发音。分别提交你所能录制的基音频率最高和最低的两个 录音文件。文件名为: 学号_a_h.wav（高音文件）和学号_a_l.wav（低音文件）。（用MathLab 编程） 1）分别对这两个文件进行观察分析。找出最高和最低基音频率位置，分别显示此时它们的 局部波形和短时频谱（按照最大值为100 归一化显示）。 要求：在时域波形上标出基音周期，并算出数值（精确到一个采样点）。在频域图上标出 基音频率。注意：标出分析波形的起始位置（精确到采样点位置），说明谱分析时所采用 的窗函数。 2）用倒谱分析法，估计语音产生模型的声道传输函数H(w)的模|H(w)|。在1)的频谱图上叠 加显示H(w), （按照最大值为100 归一化显示）。 3）用线性预测分析方法，估计语音产生模型的声道传输函数H( )的模| H( ) |。并在 1) 的频谱图上叠加显示H( ) 。(no no non )

Heap implementation in c

本代码使用matlab工具实现了一幅图片的位面图提取，且实现了在某个位面上加密信息、恢复信息的功能。并给出三幅图片的运行结果展示。(This code uses the matlab tool to achieve a picture of the bit plane map extraction, and the realization of the encrypted information in a bit plane, the function recovery information. And gives the results of running three pictures show.)

这个程序是关于连铸二冷区喷嘴模拟实验中传热系数计算的程序。(the process of continuous casting two district cooling simulation experiments nozzle heat transfer coefficient calculation procedures.)

power flow algorithm for Transmission Systems

说明：  m序列含有直流分量，将造成对辨识系统的静扰动，这通常不是所希望的(m sequence contains a DC component, will cause the static perturbation of the recognition system, this is not usually want)
