Examples

rm(list=ls())
library(blockmatrix)
A <- array(rnorm(9,mean=1),c(3,3))
B <- 0 #array(rnorm(9,mean=2),c(3,3))
C <- 0
D <- array(rnorm(9,mean=4),c(3,3))
F <- array(rnorm(9,mean=10),c(3,3))
M <- blockmatrix(names=c("A","0","D","0"),A=A,D=D,dim=c(2,2))
E <- blockmatrix(names=c("0","F","D","0"),F=F,D=D,dim=c(2,2))
E[,1] <- M[,1]
