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. )

对matlab各函数的一个串讲，对学习过但很久没用的同学回忆功能非常有用。(some classic examples make matlab easy to study )

这是用matlab实现的数据分析和统计程序，包括：用线性回归法估计一个因变量与多个自变量之间的线性关系，用多项式回归法估计一个因变量与一个自变量之间的多项式关系等 (This is achieved using matlab data analysis and statistical procedures, including: linear regression estimation one dependent variable with more than a linear relationship between the independent variables, polynomial regression is estimated that a dependent variable and an independent variable of the polynomial relationship between the)
