Detailed Description

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

General matrix class: like Array2d but with numerical methods.

Member Function Documentation

solve()

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.

eigen()

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.
