Forms the direct sum of a list of matrices
Description
The direct sum is the partitioned matrices whose diagonal submatrices are
the matrices from which the direct sum is to be formed and whose off-diagonal
submatrices are conformable matrices of zeroes. The resulting
matrix is m \times n, where m is the sum of
the numbers of rows of the contributing matrices and n is the sum of
their numbers of columns.
Usage
mat.dirsum(matrices)
Arguments
matrices
A list, each of whose component is a matrix.
Value
An m \times n matrix.

m1 <- matrix(1:4, nrow=2)
m2 <- matrix(11:16, nrow=3)
m3 <- diag(1, nrow=2, ncol=2)
dsum <- mat.dirsum(list(m1, m2, m3))
