a important ML estimation method for linear regression vie Maximum likelihood method

功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)

此程序用来在MATLAB中创建泰森多边形，并且在产生随机中心点的同时，各中心点必须满足特定的距离关系，最后输出中心点坐标以及相应的顶点坐标，以在ABAQUS中建模。(This procedure is used in MATLAB create Thiessen polygons, and at the same time generating random center point, each center must meet specific distance relationship, the final output of the center coordinates and the corresponding coordinates of the vertices to model in ABAQUS in.)

A function that takes two random variables and computes their expectation value and variance.
