Laplacian Eigenmaps [10] uses spectral techniques to perform dimensionality reduction. This technique relies on the basic assumption that the data lies in a low dimensional manifold in a high dimensional space.[11] This algorithm cannot embed out of sample points, but techniques based on Reproducing kernel Hilbert space regularization exist for adding this capability.[12] Such techniques can be applied to other nonlinear dimensionality reduction algorithms as well.

利用FFT变换，对sine2进行频谱分析，画出频谱图 利用fir源程序对输入波形sine2进行低通滤波，并将结果输出至result.dat (Using FFT transform, spectral analysis of sine2, draw the spectrum graph fir the use of the input waveform sine2 source for low-pass filtering, and the results output to result.dat)

对其它几种常用的FACTS器件也设计了阻尼控制器,并同样通过了PSASP下的仿真验证,阻尼效果很好。 ( Damping controllers of other kinds of FACTS including TCSC, STAT- COM and SSSC are also designed, which also have good effect to damping inter-area oscillation by simulation. The power oscillation between two areas is damped quickly while these FACTS are installed. )
