4.利用正态分布求\pi 正态分布(Normal distribution),也称“常态分布”,又名高斯分布(Gaussian distribution),最早由棣莫弗(Abraham de Moivre)在求二项分布的渐近公式中得到。C.F.高斯在研究测量误差时从另一个角度导出了它。P.S.拉普拉斯和高斯研究了它的性质。是一个在数学、物理及工程等领域都非常重要的概率...
Matlab - 产生高斯噪声 %正态分布(normal distribution)又名高斯分布(Gaussian distribution), % MATLAB 命令是normrnd。 %1)R=normrnd(MU,SIGMA):生成服从正态分布(MU参数代表均值,DELTA参数代表标准差)的随机数。 % 输入的向量或矩阵MU和SIGMA必须形式相同,输出R也和它们形式相同。 %2)R=normrnd(MU,SIGMA,m)...
If rho is a scalar correlation coefficient,copularndgenerates U from a bivariate Gaussian copula. Each column of U is a sample from aUniform(0,1) marginal distribution. U =copularnd('t',rho,NU,N) returns N random vectors generated from a t copula with linear correlation parameters rho and ...

Be aware, rand is generates evenly distributed random randi is the same but integer, But randn generates normally distributed random (gaussian distribution) Good Luck! 댓글 수: 2 Akif 2014년 9월 14일 Thanks Image Analyst 2014년 9월 14일 And there's also a randi() that...
