The cone of real symmetric positive-semidefinite matrices.
This cone has a dimension ``n`` associated with it, but we let ``n``
refer to the dimension of the domain of our matrices and not the
dimension of the (much larger) space in which the matrices
themselves live. In other words, our ``n`` is the ``n`` that appears
