Block Matrices

Construct a block matrix using a character string initializer.

bmat(x, rows = TRUE, sep = ",", ...)

`x`	A data vector, character string, or a list.
`rows`	Logical. If TRUE (the default) the matrix is filled by rows, otherwise the matrix is filled by columns.
`sep`	Separator string. Values within each row/column of x are separated by this string. Default is `","`.
`...`	Aditional optional arguments.

A matrix of class c("matrix", "mat").

# Construct a block matrix from matrices A1, A2, and A3
A1 <- mat('1, 1; 1, 1')
A2 <- mat('2, 2; 2, 2')
A3 <- mat('3, 3, 3, 3')
bmat('A1, A2; A3')
