Matlab code for speech processing

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.)

说明：  VMD程序，用于轴承、齿轮等振动信号的分解、降噪和重构，实现故障诊断(VMD program is used for decomposition, noise reduction and reconstruction of vibration signals such as bearings and gears to realize fault diagnosis)

说明：  将观测到的原始GPS数据，使用matlab每天求一个平均值，代码中含有实例文件！(Assistant will observe the original GPS data, use matlab to calculate an average value every day, the code contains the instance file!)

4PSK的MATLAB源码程序,其中有相应的函数,是使用蒙特卡罗方法实现的.(The MATLAB source 4PSK procedures, of which the corresponding function, is achieved using the Monte Carlo method.)
