Description

This function works in the way analogous to the diag function of Matlab.

Usage

dg(x)

If x is a number, dg returns itself. If x is a vector, a one-row matrix or a one-column matrix, dg returns a matrix with x as the main diagnol. Otherwise dg returns diag(x).

diag(matrix(2, 3))
dg(matrix(2, 3))
