提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观 法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is ​ ​ divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)

Learning for a Robot Locating a Point On a Line A machine learning program which learn to locating a robot at a predefined point on a straight line. Code is implemented in MATLAB 6.5.

在matlab中实现直方图均衡化操作及直方图匹配操作，自编代码实现运算(Histogram equalization and histogram match.)

Analogous considerations can be made for what concerns the other kind of MMI used in this project: the 1x2. Its single input waveguide is designed straight, while both output waveguides are curved as usual (with a radius of 500  m). Since the toleration curves are very similar to the precedent case, only the length and offset simulations are shown:

做一个特征提取的模拟。功能良好。非常实用(To make a feature extraction simulation. Good function. Very useful)

显示一个经验概率密度函数在输入数组中的密度分布直方图X的使用nbins箱的数目（默认pdfplot套nbins至20）。如果输入X是一个矩阵，然后pdfplot（X）的分析它的载体，并显示所有值的PDF格式。对于复杂的输入X，pdfplot（X）的显示PDF格式的(displays a histogram of the empirical probability density function (PDF) for the data in the input array X using nbins number of bins (by default pdfplot sets nbins to 20). If input X is a matrix, then pdfplot(X) parses it to the vector and displays PDF of all values. For complex input X, pdfplot(X) displays PDF of abs(X). )
