superdiag: Efficiently slices k-th diagonal from matrix A.

In rz6/CopulaHiC: Hi-C differential analysis via dependency modelling of chromatin interactions with generalized linear models

Description

Efficiently slices k-th diagonal from matrix A.

Usage

superdiag(A, k, return.idx = FALSE)

Arguments

A	matrix
k	integer diagonal to be sliced, 1 is main diagonal, positive k will yield diagonals from lower triangular matrix while negative k will yield diagonals from upper triangular
return.idx	logical whether to return indices of this diagonal

Value

numeric, vector containing entries on k-th diagonal of matrix A

Examples

mtx <- matrix(1:25, ncol = 5)
superdiag(mtx, k = 1)
superdiag(mtx, k = 2)
superdiag(mtx, k = -2)
