自适应有限元子程序，用来求解不同边界条件（第一类和第二类）的拉普拉斯方程(Adaptive finite element subroutine, used to solve different boundary conditions (first and second class) the Laplace equation)

现有的代数特征的抽取方法绝大多数采用一维的方法，即首先将图像转换为一维向量，再用主分量分析（PCA）,Fisher线性鉴别分析（LDA）,Fisherfaces式核主分量分析（KPCA）等方法抽取特征，然后用适合的分类器分类。针对一维方法维数过高，计算量大，协方差矩阵常常是奇异矩阵等不足，提出了二维的图像特征抽取方法，计算量小，协方差矩阵一般是可逆的，且识别率较高。(existing algebra feature extraction method using a majority of the peacekeepers, First images will be converted into one-dimensional vector, and then principal component analysis (PCA), Fisher Linear Discriminant Analysis (LDA), Fisherfaces audits principal component analysis (KPCA), and other selected characteristics, then use the appropriate classification for classification. Victoria against an excessive dimension method, calculation, covariance matrix is often inadequate singular matrix, a two-dimensional image feature extraction method, a small amount of covariance matrix is usually reversible, and the recognition rate higher.)

DOA 中的caponBF， 阵列信号处理的一个基本问题就是确定同时处在空间某一区域内的多个感兴趣的空间信号的方向或位置，即实现信号的分辨和定位，这也就是雷达、声纳最重要的任务之一，为了解决这一基本问题，主要采用常规波束形成法。(DOA of caponBF, a fundamental problem in array signal processing is to determine in space at the same time more interested in a particular area of space signal direction or position, namely the realization of signal resolution and positioning, which is one of the most important task in radar, sonar, in order to solve the basic problem, mainly using the conventional beam-forming method.)

随着城市经济的快速发展和城市人口的不断增加，人类活动对城市环境质量的影响日显突出。(With the city' s rapid economic development and urban population increases, human activities on urban environmental quality more evident.)

This function finds the forward kinematics of the RA-01 Robotic Arm made by Images SI, Inc. The RA-01 has five degrees of freedom. This funciton outputs two vectors. The first vector is the forward kinematics of the central position of the end effector, while the second vector is the forward kinematics of a finger of the end effector (a gripper). Note that it does not matter which finger it is as the position of one finger is simply the negative of the other hence, the value gotten for the y-direction is actually "plus or minus y".
