The RandomMatrix(r, c) command returns an $rxc$ Matrix in which all entries have integer values in the range $\mathrm{-99}..99$.

The RandomMatrix(r) command returns an $rxr$ Matrix in which all entries have integer values in the range $\mathrm{-99}..99$.

The RandomVector(d) command returns a d-dimensional Vector in which all entries have integer entries in the range $\mathrm{-99}..99$.

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

If the dimension is not provided, it defaults to 0.
