The ZeroMatrix(r, c) command returns an $rxc$ Matrix in which all the entries are zero.

The ZeroMatrix(r, r) command returns an $rxr$ Matrix in which all the entries are zero.

The ZeroMatrix() command returns an $0x0$ Matrix.

The ZeroVector(d) command returns a d-dimensional Vector in which all the entries are zero.

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

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