Thank you but I want to create a matrix (4,4) or (8,8) not just only a (2,2)
matrix...

provide an m0 matrix of the appropriate dimensions and change 2 to the
new dimension in the relevant lines.

Hi, I have a question for my simulation problem:
I would like to generate a positive (or semi def positive) covariance
matrix, non singular, in wich the spectral decomposition returns me the same
values for all dimensions but differs only in eigenvectors.
Ex.
sigma
[,1] [,2]
[1,]
Sorry in the previuos message I've inverted: I would like generate ...
same eigenvectors and different eigenvalues

Try this:
m0 - 5 + matrix(c(.05, -.05, -.05, .05), 2)
m0.values - eigen(m0)$values
with(eigen(matrix(rnorm(4),
