template<typename Derived>
class Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >
Base class providing read-only coefficient access to matrices and arrays.
- Template Parameters
-
Derived | Type of the derived class |
- Note
- ReadOnlyAccessors Constant indicating read-only access
This class defines the operator()
const
function and friends, which can be used to read specific entries of a matrix or array.

◆ coeff() [1/2]
template<typename Derived >
◆ coeff() [2/2]
template<typename Derived >
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 .
