人工产生swissroll数据集，方便一些降维方法的效果验证(Swissroll generate artificial data sets to facilitate some of the effects of dimensionality reduction methods to verify)

To compute velocity and displacement from Acceleration data In put : Acceleration data and sampling rate in time (delta time) Out put : time. acceleration, velocity, and displacement.

本代码是在matlab平台上对数字进行检测识别(This code is in matlab platform for detection of digital identification)

sunjun编写的量子粒子群算法，MATLAB程序，简单易懂，注释清晰。(QPSO.m coded by Sun Jun, a efficient and effective algorithm, also a Swarm-Intelligent algorithm.)

说明：  visual c++ 开发的MemFile的源代码， 喜欢的可以下(visual c MemFile development of the source code, like they can)

不考虑不平衡磁拉力（UMP），转子系统在自身的质量、阻尼、弹簧等作用下，轴心轨迹求解方法(unbalanced magnetic pull is not considerated and rotor center orbit is gotten)

这是关于Matlab的信号处理的电子书，里面介绍了关于Matlab的信号变换和调制，模拟滤波器等。(This is the Matlab signal processing on the e-book, which introduced the report on Matlab and modulation of the signal transformation, such as analog filters.)

自己搭的三相锁相环模拟电路，作业经过运行验证，能够很迅速的锁定电压电流相位。(Take their own three-phase PLL analog circuits, after running the verification, the lock can be very rapid phase of voltage and current.)
