Base class providing read/write coefficient access to matrices and arrays.
Derived | Type of the derived class |
This class defines the non-const operator()
function and friends, which can be used to write specific entries of a matrix or array. This class inherits DenseCoeffsBase<Derived, ReadOnlyAccessors> which defines the const variant for reading specific entries.

Short version: don't use this function, use operator[](Index) instead.
Long version: this function is similar to operator[](Index), 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).

This is synonymous to operator[](Index).
This method is allowed only for vector expressions, and for matrix expressions having the LinearAccessBit.
