Diagonal Tensor

Creates a tensor with the vector v on its superdiagonal and zeros elsewhere, mirroring the MATLAB Tensor Toolbox tendiag.

Usage

tendiag(v, dims = NULL)

Arguments

v

Numeric vector of diagonal values.

dims

Optional integer vector of dimensions. Defaults to a square matrix-shaped tensor c(length(v), length(v)). Each entry must be at least length(v).

Value

A Tensor with v on the superdiagonal.

Examples

D <- tendiag(1:3, c(3, 3, 3))
