gsAsMatrix< T, _Rows, _Cols > Class Template Reference

Detailed Description

template<class T, int _Rows, int _Cols>
class gismo::gsAsMatrix< T, _Rows, _Cols >

Creates a mapped object or data pointer to a matrix without copying data.

This allows for re-indexing the matrix. No copying is taking place and the original matrix remains untached.

Template Parameters

T	coefficient type

Inherits Map< gsEigen::Matrix< T, _Rows, _Cols > >.

Member Function Documentation

colMinor()

template<class T , int _Rows, int _Cols>

void colMinor ( index_t  j, ColMinorMatrixType &  result  ) const

inline

Returns the jth column minor, i.e. the matrix after removing row j from the matrix. After the operation the column size of the matrix is one less.

firstMinor()

template<class T , int _Rows, int _Cols>

void firstMinor ( index_t  i, index_t  j, FirstMinorMatrixType &  result  ) const

inline

Returns the (i,j)-minor, i.e. the matrix after removing row i and column j from the matrix. After the operation the row and column size of the matrix is one less.

rowMinor()

template<class T , int _Rows, int _Cols>

void rowMinor ( index_t  i, RowMinorMatrixType &  result  ) const

inline

Returns the ith row minor, i.e. the matrix after removing row i from the matrix. After the operation the row size of the matrix is one less.
