fatdiag: Fat Matrix Diagonals

In bquast/diagonals: Block Diagonal Extraction or Replacement

Fat Matrix Diagonals

Description

Fat Matrix Diagonals

fatdiag set

Usage

fatdiag(x = 1, steps = NULL, size = NULL, nrow = NULL, ncol = NULL)

fatdiag(x, steps = NULL, size = NULL, on_diagonal = TRUE) <- value

Arguments

x	a matrix where the dimensions are integer multiples of size or integer dividors of steps
steps	the required number of steps (block matrices) across the diagonal
size	the width or height of the matrix being dropped over the diagonal of matrix x
nrow	the number of rows
ncol	the number of columns
on_diagonal	should the operation be applied to the elements on the fat diagonal.
value	replacement value

Details

Either steps or size is expected to be provided.

Functions

• fatdiag<-: the set version of fatdiag

Examples

fatdiag(12, steps=3)

( m <- matrix(111, nrow=6, ncol=9) )
fatdiag(m, steps=3) <- 5

fatdiag(m, steps=3)

fatdiag(12, size=4)

fatdiag(12, size=c(3,4) )
