This is the class of the matrix and the records of the right and
left elementary diformations on it. There is a subclass of the quintet
of matrices (Algebra::MatrixAlgebraQuint).
Creates the triplet object of matrix as the body,
left as the record of the left(row) deformation and
right as the record ofthe right(column) deformation.
This is the class of the matrix and the records of the right and
left elementary diformations on it and the reverses of them.
There is a superclass of the triplet
of matrices (Algebra::MatrixAlgebraTriplet).
