This function builds a blockmatrix

Description

This function builds a blockmatrix

Usage

  blockmatrix(dim, value = NULL, names = NULL, list = NULL,
    use.as.blockmatrix = TRUE, adjust_zero = TRUE,
    add_zero_matrix = FALSE, zero_element = "0", ...)

Arguments

dim

dimension of a block-matrix

value

matrix containing the indices (names) of blockmatrix element. If missing, it is NULL (Default). (sse value

names

charcarcter vector containing the names for each matrix-type element of the block-matrix

list

list containing the matrices to be inserted into the block-matrix. If NULL (Default) the matrix are faken from ...

use.as.blockmatrix

logical value. If TRUE (Default) the method as.blockmatrix for blockmatrix object is applied to the output blockmatrix before being returned.
