Matrix types and operations
Matrix types (special types like bidiagonal/tridiagonal are not listed):
- Real - general (nonsymmetric) real
- Complex - general (nonsymmetric) complex
- SPD - symmetric positive definite (real)
- HPD - Hermitian positive definite (complex)
- SY - symmetric (real)
- HE - Hermitian (complex)
- BND - band
Operations:
- TF - triangular factorizations (LU, Cholesky)
- OF - orthogonal factorizations (QR, QL, generalized factorizations)
- EVD - eigenproblems
- SVD - singular value decomposition
- GEVD - generalized EVD
- GSVD - generalized SVD
| Real | Complex | SPD | HPD | SY | HE | BND | TF | OF | EVD | SVD | GEVD | GSVD | |
