* \param XprType the type of the expression in which we are taking a block

* This class represents an expression of either a fixed-size or dynamic-size block. It is the return
|
| ykuroda |
0:13a5d365ba16
|
26
|
* type of DenseBase::block(Index,Index,Index,Index) and DenseBase::block<int,int>(Index,Index) and
|
| ykuroda |
0:13a5d365ba16
|
27
|
* most of the time this is the only way it is used.

|
28
|
*
|
| ykuroda |
0:13a5d365ba16
|
29
|
* However, if you want to directly maniputate block expressions,
|
| ykuroda |
0:13a5d365ba16
|
30
|
* for instance if you want to write a function returning such an expression, you
|
| ykuroda |
0:13a5d365ba16
|
31
|
* will need to use this class.
|
| ykuroda |
0:13a5d365ba16
|
32
|
*
|
| ykuroda |
0:13a5d365ba16
|
33
|
* Here is an example illustrating the dynamic case:
|
| ykuroda |
0:13a5d365ba16
|
34
|
* \include class_Block.cpp
|
| ykuroda |
0:13a5d365ba16
|
35
|
* Output: \verbinclude class_Block.out
|
| ykuroda |
0:13a5d365ba16
|
36
|
*
|
| ykuroda |
0:13a5d365ba16
|
37
|
* \note Even though this expression has dynamic size, in the case where \a XprType
|
| ykuroda |
0:13a5d365ba16
|
38
|
* has fixed size, this expression inherits a fixed maximal size which means that evaluating
|
| ykuroda |
0:13a5d365ba16
|
39
|
* it does not cause a dynamic memory allocation.
|

|
| ykuroda |
0:13a5d365ba16

|
* Here is an example illustrating the fixed-size case:
|
| ykuroda |

|
42
|
* \include class_FixedBlock.cpp
|
