针对DEM的建模问题，将高程看作区域化变量，应用地质统计学中普通克里格研究了一个山区高程空间变异分析及其插值。(DEM for modeling will be seen as a regionalized variable elevation, application of ordinary kriging in geostatistics research a mountain elevation spatial variability analysis and interpolation.)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

说明：  双PI闭环PWM整流器，可完美运行,网侧THD3.8%，直流侧电压启动超调量1%左右(Double PI closed-loop PWM rectifier, perfect operation, thd3.8% at grid side, 1% of DC side voltage start-up overshoot)

这是我上传的两篇关于HHT应用和HHT局限性的文章，上传出来大家一起看看啊(This is my upload HHT about two applications and the limitations of article HHT, upload them to see if everybody ah)

用matlab编程的自适应直方图程序，经过试验了，还可以。。可以下载来应用看看。(Adaptive histogram using matlab programming procedures, tested, and was quite good. . Can be downloaded to apply a look.)

Flexible construction of girth-six QC-LDPC Codes(The program constructs girth-six QC-LDPC codes given row-weight,k, column-weight,j, and sub-matrix size,m. The obtained parity-check matrix is stored in H. The construction has flexibility in that j,k and m can be varied.The program achieves girth-six by applying the row-column constraint. There are m rows in j submatrices. No two rows should share the same column more than once. This constraint is applied to avoid 4-cycles. The construction has flexibility in that j,k and m can be varied.)

该程序初步实现了M序列的生成，并且详细地进行了频域法的系统辨识分析。(The program is the initial realization of the M-sequence generation, and detail the frequency domain method of system identification analysis.)

this is a matlab program for a feedback and control systems laboratory subject
