Word description

Tests if the object is a regular (well-formed, rectangular, etc) matrix. A regular matrix is a sequence with an equal number of elements in every row, and an equal number of elements in every column, such that there are no empty slots.

Notes

The null-matrix is considered regular, because of semantic requirements of the matrix implementation.

Examples

The example is an irregular matrix, because the rows have an unequal number of elements.
