矩阵变换器的模型预测控制，运行时先运行M文件，再运行仿真模型。(Matrix converter model predictive control, run the first run M file, and then run the simulation model.)

结合DCT和NNC进行人脸识别。先利用DCT提取特征，然后利用最近邻分类器分类，在ORL人脸库上测试效果不错。(The combination of DCT and NNC for face recognition. First DCT Feature Extraction, and then use the nearest neighbor classifiers, good test results on the ORL face database.)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
