Block-Diagonal Matrix and Multivariate Skew Normal
Dear R-users,
Does anybody know how to construct a block-diagonal matrix (with the blocks being different matrixs, concerning the dimension and the values) ?
I would like to know also if there is any package that generates values from a multivariate skew normal distribution.
Thanks all,
Caio

a trick ??
Dear R users,
Suppose i have an A square matrix rxr. I want to obtain a block matrix
B (pxr,pxr) where
the p diagonal blocks are A and the others values are 0.
I would like to do something like : diag(A,ncol=pr, nrow=pr)
How can i do it ??
Thanks in advance,
Olivier.
