the same as its matrix representation in the superalgebra::
sage: set_random_seed()
- sage: x = random_eja(field=QQ).random_element()
+ sage: x = random_eja(field=QQ,orthonormalize=False).random_element()
sage: A = x.subalgebra_generated_by(orthonormalize=False)
sage: y = A.random_element()
sage: actual = y.to_matrix()
