| <h2>Eigenvalue Problem Solvers - EPS</h2> |
| <h2>Eigenvalue Problem Solvers - EPS: <a href="../../../src/eps/examples/tutorials/index.html">Examples</a></h2> |
| <p> |
| The Eigenvalue Problem Solver (EPS) is the object provided by SLEPc for specifying an eigenvalue problem, either in standard or generalized form. It provides uniform and efficient access to all of the eigensolvers included in the package. |

| <h2>Singular Value Decomposition Solvers - SVD: <a href="../../../src/svd/examples/tutorials/index.html">Examples</a></h2> |
| <p> |
| The Singular Value Decomposition Solver (SVD) is very similar to the EPS object, but intended for the computation of the partial SVD of a rectangular matrix. With this type of object, the user can specify an SVD problem and solve it with any of the different solvers encapsulated by the package. Some of these solvers are actually implemented through calls to EPS eigensolvers. |

| <h2>Quadratic Eigenvalue Problem Solvers - QEP</h2> |
| <h2>Quadratic Eigenvalue Problem Solvers - QEP: <a href="../../../src/qep/examples/tutorials/index.html">Examples</a></h2> |
| <p> |
| The Quadratic Eigenvalue Problem (QEP) solver is the object provided by SLEPc for specifying a quadratic eigenvalue problem. Apart from the specific solvers for this type of problems, there is an EPS-based solver, i.e., it uses a solver from EPS to solve a generalized eigenproblem obtained after linearization. |

| <h2>Spectral Transformation - ST</h2> |
| <h2>Spectral Transformation - ST: <a href="../../../src/st/examples/tutorials/index.html">Examples</a></h2> |
| <p> |
| The Spectral Transformation (ST) class encapsulates the functionality required for acceleration techniques based on the transformation of the spectrum. As explained in the SLEPc Users Manual, the eigensolvers implemented in EPS work by applying an operator to a set of vectors and this operator can adopt different forms. The ST object handles all the different possibilities in a uniform way, so that the solver can proceed without knowing which transformation has been selected. |
