生成服从t(Student’s t Distribution,这里student不是学生的意思,而是cosset.W.S.的笔名)分布的随机数。t分布只有一个参数:自由度v 基本语法:trnd(v,[M,N,P,…]) t分布比正太分布要“瘦”,随着自由度v的增大,t分布逐渐变胖,当自由度为正无穷时,它就变成标准正态分布了。 8、betarnd() 生成服从beta分布...

Create a probability distribution object NormalDistribution by fitting a probability distribution to sample data (fitdist) or by specifying parameter values (makedist). Then, use object functions to evaluate the distribution, generate random numbers, and so on. Work with the normal distribution interacti...
The typical assumption for a complex-valued Gaussian random vector is to split the variance equally among the real and imaginary parts. Let the variance be sigma2. z = sqrt(sigma2/2)*(randn(1000,1)+1j*randn(1000,1)); If you have the Communications Toolbox, see awgn()....
在这一部分,我们就来描述源于Dr Kalman 的卡尔曼滤波器。下面的描述,会涉及一些基本的概念知识,包括概率(Probability),随即变量(Random Variable),高斯或正态分配(Gaussian Distribution)还有State-space Model等等。但对于卡尔曼滤波器的详细证明,这里不能一一描述。
