Create a block diagonal matrix

Description

Combine a list of matrices into a block diagonal matrix

Usage

block_diagonal(mat_list, fill = 0)

Arguments

mat_list	The list of matrices in the order they appear from top-right to bottom-left in the final matrix
fill	The value of entries in the off-block entries; defaults to 0

Details

The matrices provided in mat_list will be arranged as block matrices with the first listed matrix at the top-right and the last matrix at the bottom left. The entries that are not in each block are filled with fill, which defaults to 0.

Value

A block-diagonal matrix
