diag.block: Constructs a block diagonal matrix

In wolfganglederer/simex: SIMEX- And MCSIMEX-Algorithm for Measurement Error Models

Description

The function takes a list and constructs a block diagonal matrix with the elements of the list on the diagonal. If d is not a list then d will be repeated n times and written on the diagonal (a wrapper for kronecker())

Usage

diag.block(d, n)

Arguments

d	a list of matrices or vectors, or a matrix or vector
n	number of repetitions

Value

returns a matrix with the elements of the list or the repetitions of the supplied matrix or vector on the diagonal.
