说明：  利用AMDF法求语音信号的基音周期（结果为时频图）(Pitch detection by AMDF algorithm)

Modified Gram-Schmidt (MGS)正交化法是利用已有正交基计算新的正交基。既能选择相关特征，又能排出已选特征对后续特征选择的影响。(Modified Gram-Schmidt (MGS)orthogonalization gives new orthogonal basis through original orthogonal basis. It can do the feature selection and eliminate the impact on choosing new feature vector by the selected one.)

A matlab script to calculate the performance of a multi-stage rocket. payloads, veloicties, all dem good stuffs.

本程序为产生多途信号，并对多个信号进行叠加，并混入一定信噪比的噪声。然后对得到的信号进行频谱分析和相关分析。(The procedure for producing multi-path signal, and the superposition of multiple signals, and mixed with a certain signal to noise ratio of the noise. Then the resulting signal spectrum analysis and correlation analysis.)

UWB，超宽带信号分析必用的子函数，第13部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 13!)

this is matlab version of removal of noise

it is a single-phase inverter with hysteresis
