光伏并网PQv模型

是一个matlab中的power system 中搭建的一个模型。可以仿真35KV电力系统线路发单项短路故障、两项短路故障、和三项短路故障的短路电流电压波形。(This is a model of building a matlab power in system. Simulation of 35kV Power line system billing short-circuit fault, two short circuit fault, and three short circuit fault short-circuit current and voltage waveforms. )

利用matlab，对语音信号进行端点检测和修剪(Speech endpoint trimming)

编写M文件，创建如下图形窗口，分别绘制如下图所示的曲线。 （1）曲线y=sin(t)sin(9t)，要求采用红色，点线。横坐标取值范围[0~ ]，标注x轴、y轴并加标题。 （2）一组余弦曲线，其振幅分别为0.4，0.6和0.8。横坐标取值范围[0~2 ]。添加图例与标题。进入图形编辑状态，调整图例的位置。 （3）分别绘制peaks函数的曲面图和网格线图。对曲面图做平滑处理，并添加标题与colorbar。 (Write M file, create the following graphics window, curves were plotted as shown below. (A) the curve y = sin (t) sin (9t), require the use of a red dotted line. The abscissa in the range [0 ~  ], labeled x-axis, y-axis and a title. (2) a set of a cosine curve, and the amplitude was 0.4, 0.6, 0.8. Abscissa value range [0 ~ 2  ]. Add a legend and title. Into the graphical editing mode, adjust the position of the legend. (3) were drawn surface chart peaks function and grid line graph. Surface charts do for smoothing and add titles and colorbar.)

静态背景下的高精度视频目标是实时检测与轮廓提取，matlab源代码实现。 (High-precision static background video object detection and contour extraction in real time, matlab source code.)

QC-LDPC码编程，围长为8，列重为3，无4环(The program contructs column-weight three girth-eight QC-LPDC codes given row-weight and sub-matrix size. row-weights and sub-matrices sizes are variable.)

牛顿-拉夫逊法在数学上是求解非线性代数方程组的有效方法，其要点是把非线性方程求解过程变成反复地对相应的线性方程进行求解的过程。(Newton- Raphson method in mathematics is an effective method for solving nonlinear algebraic equations, the point is that the non-linear equation solving process into the process repeated for the corresponding linear equation solving.)
