An Analytical Model to Predict the Probability Density Function of Elevation Angles for LEO Satellite Systems-Based on earth-satellite geometry, an analytical model is proposed to predict the probability density function (pdf) of elevation an

用给定的多项式，如y=x3-6x2+5x-3，在[-1，1]上等间隔产生20组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(-5,5)均匀分布随机数)。请 (1)对xi和添加了随机干扰的yi作3次多项式拟合，与原系数比较。 -With the given polynomial, such as y=x3-6x2+5x-3, [-1, 1] intervals of 20 sets of data (Xi, Yi, i=1,2,... , n), and
