介绍了几款数学软件的使用，其中包括mathematica matlab 以及SAS，内容涵盖了数值处理和求解方程组等。(Describes the use of several mathematical software, including mathematica matlab and SAS, which covers the numerical processing and solving equations and so on.)

PCA主成分分析方法来处理手势向量，来获得手势的特征向量，即主要成分(PCA principal component analysis method)

说明：  A set of m files for solve rate equations.

将角度和幅度的二维数组画成dB值的polar图( POLARDB Polar coordinate plot. POLARDB(THETA, RHO) makes a plot using polar coordinates of the angle THETA, in radians, versus the radius RHO in dB. The maximum value of RHO should not exceed 1. It should not be normalized, however (i.e. its max. value may be less than 1). POLAR(THETA,RHO,S) uses the linestyle specified in string S. See PLOT for a description of legal linestyles. )
