The ConstantMatrix(s, r, c) command returns an $rxc$ Matrix in which all entries have the value s.

The ConstantMatrix(s, r) command returns an $rxr$ Matrix in which all entries have the value s.

The ConstantMatrix(s) command returns an $0x0$ Matrix.

The ConstantVector(s, d) command returns a d-dimensional column Vector in which all entries have the value s.

The ConstantVector[row](s, d) command behaves like ConstantVector(s, d) except that a row Vector is returned.  If the orientation option is omitted or if ConstantVector[column](s, d) is used, a column Vector is returned.

If the dimension is not provided, it defaults to zero.
