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 [inline]

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  )  [inline]

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.
