DIAG

Type: Command
Description: Vector to Matrix Diagonal Command: Takes an array and a specified dimension and returns a
matrix whose major diagonal elements are the elements of the array.
Real number dimensions are rounded to integers. If a single dimension is given, a square matrix
is returned. If two dimensions are given, the proper order is { number of rows, number of columns }.
No more than two dimensions can be specified.
If the main diagonal of the resulting matrix has more elements than the array, additional diagonal
elements are set to zero. If the main diagonal of the resulting matrix has fewer elements than the
array, extra array elements are dropped.
