In pracma: Practical Numerical Math Functions

Block Diagonal Matrix

Description

Build a block diagonal matrix.

Usage

blkdiag(...)

Arguments

...	sequence of non-empty, numeric matrices

Details

Generate a block diagonal matrix from A, B, C, .... All the arguments must be numeric and non-empty matrices.

Value

a numeric matrix

Note

Vectors as input have to be converted to matrices before. Note that as.matrix(v) with v a vector will generate a column vector; use matrix(v, nrow=1) if a row vector is intended.
