Matrices[{d1, d2}]
represents the domain of matrices of dimensions ×.

Matrices[{d1, d2}, dom]
represents the domain of matrices of dimensions ×, with components in the domain dom.

Matrices[{d1, d2}, dom, sym]
represents the subdomain of matrices × with symmetry sym.


  • Valid dimension specifications in Matrices[{d1, d2}, dom, sym] are positive integers. It is also possible to work with symbolic dimension specifications.
  • Valid component domain specifications dom are either Reals or Complexes. Matrices[{d1, d2}] uses Complexes by default.
  • For matrices, the symmetry sym can be either Symmetric[{1, 2}], Antisymmetric[{1, 2}], or , which represents the trivial symmetry.
  • If the symmetry sym is nontrivial, then the dimensions and must coincide.
