Generate a multidimensional normal random matrix with the help of rmvnorm ()

Install the mvtnormalization package

> install.packages ("mvtnorm") > library (mvtnorm)

Generate random matrix

X=rmvnorm (length (mean)), sigma=diag (length).

For example

> x = rmvnorm (5 recordrep (0BE3), diag (3)) > x [, 1] [, 2] [, 3] [1,] 0.2319038-0.22077218 0.5232609 [2,] 0.2374806-2.33881461-0.6796371 [3,] 0.3614914-0.07900088 0.2848471 [4,] 1.4700363-1.26901580-0.4505197 [5,]-1.5877496 0.01318156-2.1257104

Mean=rep (0MagneNrow (sigma), can also change the size of the mean vector, for example: rep (1meme2), or rep (2meme3). Even negative numbers.
