Base class for Map and Block expression with direct access.
Expression classes inheriting MapBase must define the constant PacketAccess, and type AlignedDerivedType in their respective ei_traits<> specialization structure. The value of PacketAccess can be either:
AlignedDerivedType should correspond to the equivalent expression type with PacketAccess being ForceAligned.Definition at line 43 of file MapBase.h.

| anonymous enum |
| IsRowMajor | |
| PacketAccess | |
| RowsAtCompileTime |
The number of rows at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. |
| ColsAtCompileTime |
The number of columns at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. |
| SizeAtCompileTime |
This is equal to the number of coefficients, i.e. the number of rows times the number of columns, or to Dynamic if this is not known at compile-time.

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

Short version: don't use this function, use operator()(int,int) const instead.
Long version: this function is similar to operator()(int,int) 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()(int,int) const .

The LoadMode parameter may have the value Aligned or Unaligned. Its effect is to select the appropriate vectorization instruction. Aligned access is faster, but is only possible for packets starting at an address which is a multiple of the packet size.
