说明：  实现声音时域分析，达到对声音信号短时能量的图形描绘分析(Time domain analysis to achieve the sound, the sound signal to the graphic description of short-term energy)

1. 安装MATLAB软件。安装时，将MATLAB安装在C:MatlabR12目录下 Matlab的详细安装方法见有关安装手册 2. 拷贝文件:即将光盘中的/ctl/program和/ctl/functions下的 文件复制到用户目录下（例如，D:User) 3. 设置路径:先运行MATLAB,在桌面操作环境下，点击File下拉式菜单 的Set path选项，添加用户目录（例如，D:User)(含子目录ctl等） 到MATLAB的工作路径 4. 运行程序:先运行MATLAB,如第3步已运行，可直接键入示例命令。 例如，键入ex1_1等 5. 阅读教材，并对示例进行操作。">

小程序，matlab编的，用于解常微分方程的问题(Small program, matlab compiled for the solution of ordinary differential equations of the problem)

说明：  matlab using tools used

求解常微分方程的龙格-库塔（Runge - Kutta）法(Ordinary differential equations RungeKutta method)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

分析和仿真：双开关管单端正激、单端反激、推挽和全桥四种隔离型直直电路和三输出的单端反激型直-直变换器(Analysis and simulation: a single-ended forward double switch, single-ended single-ended flyback, push-pull and full-bridge circuit of four straight and three isolated output flyback DC- DC Converters)

周期信号的合成、分解与Gibbs现象.ppt

说明：  对梁进行动力学分析，计算梁在集中力的作用下的变形(Dynamic analysis of the beam, for beam under the action of concentrated forces in the deformation)
