Detailed Description

template<typename Derived>
class Eigen::DenseCoeffsBase< Derived, DirectAccessors >

Base class providing direct read-only coefficient access to matrices and arrays.

Template Parameters:
DerivedType of the derived class
DirectAccessorsConstant indicating direct access

This class defines functions to work with strides which can be used to access entries directly. This class inherits DenseCoeffsBase<Derived, ReadOnlyAccessors> which defines functions to access entries read-only using operator() .

CoeffReturnType coeff ( Index  row,
Index  col 
) const [inline, inherited]

Short version: don't use this function, use operator()(Index,Index) const instead.

Long version: this function is similar to operator()(Index,Index) const , but without the assertion. Use this for limiting the performance cost of debugging code when doing repeated coefficient access. Only use this when it is guaranteed that the parameters row and col are in range.

If EIGEN_INTERNAL_DEBUGGING is defined, an assertion will be made, making this function equivalent to operator()(Index,Index) const .

See also:
operator()(Index,Index) const, coeffRef(Index,Index), coeff(Index) const
CoeffReturnType coeff ( Index  index) const [inline, inherited]

Short version: don't use this function, use operator[](Index) const instead.

Long version: this function is similar to operator[](Index) const , but without the assertion. Use this for limiting the performance cost of debugging code when doing repeated coefficient access. Only use this when it is guaranteed that the parameter index is in range.

If EIGEN_INTERNAL_DEBUGGING is defined, an assertion will be made, making this function equivalent to operator[](Index) const .

operator[](Index) const, coeffRef(Index), coeff(Index,Index) const
Index cols ( void  ) const [inline, inherited]
Returns:
the number of columns.
