## Detailed Description

### template<class T = ftype> class clipper::Matrix< T >

General matrix class: like Array2d but with numerical methods.

## Member Function Documentation

template<class T>
 std::vector< T > clipper::Matrix< T >::solve ( const std::vector< T > & b ) const

equation solver (square matrices only)

Solve the system of linear equations Ax=b for x Uses elimination. Only suitable for small systems.

template<class T >
 std::vector< T > clipper::Matrix< T >::eigen ( const bool sort = `true` )

eigenvalue calculation (square symmetric matrices only)

Find the Eigenvalues and Eigenvectors of the matrix. Uses the Jacobi method. Only suitable for small systems (dimension<20). The matrix is replaced by the matrix of eigenvectors (as columns).

Parameters:
 sort Sort the eigenvalues and vectors, smallest first. (default=true)
Returns:
Vector of eigenvalues.
