R = geornd(P) generates geometric random numbers with probability parameter P. P can be a vector, a matrix, or a multidimensional array. The size of R is the size of P. The geometric distribution is useful when you want to model the number of successive failures preceding a success, wher...
X = rand(s,___) generates numbers from random number stream s instead of the default global stream. To create a stream, use RandStream. You can specify s followed by any of the input argument combinations in previous syntaxes.Examples collapse all Matrix of Random Numbers Copy Code Copy ...

n— Number of random vectors to return positive scalar value Number of random vectors to return, specified as a positive scalar value. If you specify the copula type as 'Gaussian' or 't', and rho is a p-by-p correlation matrix, then u is an n-by-p matrix. If you specify the copu...
Number of multivariate random numbers, specified as a positive scalar integer. n specifies the number of rows in R. Data Types: single | double Output Arguments collapse all R— Multivariate normal random numbers numeric matrix Multivariate normal random numbers, returned as one of the following: ...
使用matlab里面的rand函数可以生成随机数函数。rand函数的用法 ：（1）命令：rand(N)，rand(M,N)等 （2）对于rand(N)，通过help rand得到的解释是：R = rand(N) returns an N-by-N matrix containing pseudorandom values drawn from the standard uniform distribution on the open interval(0,1...
Create a 2-by-3 matrix of single-precision numbers. Get p = single([0.1 -3 2.5; 1.2 -3.4 6]); Create a random number stream whose seed is zero. Get s = RandStream('mcg16807','Seed',0); Use the stream to generate an array of random numbers that is the same size and data...
ones() function is used to generate a matrix with all 1s, and the zeros() function is used to generate a matrix with all 0s. The rand() function is used to generate a random matrix uniformly distributed in the (0,1) interval, and the eye() function generates the identity matrix. ...
