id_impulsive

共有5个程序，分别是从文件提取散点画球（椭球），散点画压力云图，散点画散点位置及速度分布图，散点画密度分布图，以及从数据文件中提取特定散点的程序，这是一套程序，可对大量散点数据进行处理。(There are five programs, which are extracted from the file powder stippling ball (ellipsoid), scattered cloud pressure stipple, stipple scatter scattered distribution of position and velocity, bulk density stipple maps and data files extracted from the scatter-specific procedures This is a process, a large number of discrete data can be processed.)

MATLAB环境下的数值分析教学软件开发(MATLAB environment teaching numerical analysis software development)

msk demodulation technique using OQPSK

说明：  matlab实现对声音信号短时能量，短时过零率的计算。(matlab voice signals to achieve short-term energy, zero-crossing rate of short-term calculations.)

利用球贝塞尔函数和汉克尔函数计算低频、中频、高频的雷达散射截面。(The calculation of the radar cross section of low frequency, intermediate frequency, high frequency by using the spherical Bessel function and Hankel function.)

说明：  遗传算法得源代码,不是用MATLAB编得,而是用VC++编程.(genetic algorithm in the source code, instead of being MATLAB, but programming with VC.)

将DE405数据文件转换为Matlab的.mat文件的函数，方便Matlab的读取(DE405 data file is converted to the Matlab MAT file function to facilitate the Matlab reads)

利用SVM进行多分类的matlab 程序，m文件(Multi classification by using SVM matlab program, the m file)

Stability criteria Nyquist plot in Matlab.

程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。(Program uses a two-layer loop on calculate displacement spectra. Cycle based on seismic waves obtained the previous step under the displacement, velocity and acceleration are next after the interval velocity and Acceleration outer loop implementation in different natural period of structure (frequency) the response under earthquake wave.)
