timefreq

用root—music方法计算正弦信号的频率估计(root-music )

自己建立的clark变换模块，根据TI公司永磁电动机例程编写(clark transform model created by myself， based on TI s permanent magnet motor routine)

用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径，缺少圆弧起始角及终止角，并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)

强大的响度计算工具包。可以计算稳态的响度和瞬态的响度。并且可以将响度表示在时域上。(Loudness calculated powerful toolkit. Can calculate the loudness of steady state and transient loudness. Loudness and can be expressed in the time domain.)

包括matlab环境下的步态识别代码，视频序列、ppt展示及相关文献(Including gait recognition code in the Matlab environment, the video sequence, ppt show and related literature)

poiseuille流，LBM方法matlab实现(poiseuille flow, LBM method matlab realize)

this is matlab code cyclic 1511

对示波器或其他设备在实验中接收并储存的离散信号进行绘图，行程信号曲线图(Oscilloscope or other device is received and stored in the experiment drawing discrete signals, the signal graph stroke)

基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置(RSSI-based positioning, known to launch the node transmission signal strength, the receiving node according to received signal strength, transmission loss calculated using the theory or experience loss of signal propagation model will spread into the distance and then calculate the location of the node)
