Detailed Description

template<typename MatrixType, int _Direction>
class Eigen::Homogeneous< MatrixType, _Direction >

Expression of one (or a set of) homogeneous vector(s)

Parameters:
MatrixTypethe type of the object in which we are making homogeneous

This class represents an expression of one (or a set of) homogeneous vector(s). It is the return type of MatrixBase::homogeneous() and most of the time this is the only way it is used.

MatrixBase::homogeneous()

Member Typedef Documentation

typedef Matrix<typename internal::traits<Homogeneous< MatrixType, _Direction > >::Scalar, internal::traits<Homogeneous< MatrixType, _Direction > >::RowsAtCompileTime, internal::traits<Homogeneous< MatrixType, _Direction > >::ColsAtCompileTime, AutoAlign | (internal::traits<Homogeneous< MatrixType, _Direction > >::Flags&RowMajorBit ? RowMajor : ColMajor), internal::traits<Homogeneous< MatrixType, _Direction > >::MaxRowsAtCompileTime, internal::traits<Homogeneous< MatrixType, _Direction > >::MaxColsAtCompileTime > PlainObject [inherited]

The plain matrix type corresponding to this expression.

This is not necessarily exactly the return type of eval(). In the case of plain matrices, the return type of eval() is a const reference to a matrix, not a matrix! It is however guaranteed that the return type of eval() is either PlainObject or const PlainObject&.

typedef Matrix<Scalar,EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime), EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime)> SquareMatrixType [inherited]

type of the equivalent square matrix

Member Function Documentation

ArrayWrapper<Homogeneous< MatrixType, _Direction > > array (  ) [inherited]
Returns:
an Array expression of this matrix
See also:
ArrayBase::matrix()

Definition at line 316 of file MatrixBase.h.

Index diagonalSize (  ) const [inherited]
Returns:
the size of the main diagonal, which is min(rows(),cols()).
See also:
rows(), cols(), SizeAtCompileTime.

Homogeneous< MatrixType, _Direction > & lazyAssign ( const Flagged< OtherDerived, 0, EvalBeforeAssigningBit > &  other ) [inherited]

Definition at line 477 of file MatrixBase.h.

bool operator!= ( const MatrixBase< OtherDerived > &  other ) const [inherited]
Returns:
true if at least one pair of coefficients of *this and other are not exactly equal to each other.
Warning:
When using floating point scalar values you probably should rather use a fuzzy comparison such as isApprox()
See also:
isApprox(), operator==

Definition at line 295 of file MatrixBase.h.

bool operator== ( const MatrixBase< OtherDerived > &  other ) const [inherited]
Returns:
true if each coefficients of *this and other are all exactly equal.
Warning:
When using floating point scalar values you probably should rather use a fuzzy comparison such as isApprox()
