Shape
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
* array, matrix and vector have a method shape() that returns a `shape_type` object
|
||
|
|
i.e. a mini_vector<size_t,rank>. DOCUMENT THIS ?
|
||
|
|
|
||
|
|
* Example::
|
||
|
|
|
||
|
|
array<double,2> A(2,3);
|
||
|
|
A.shape()[0] == 2;
|
||
|
|
A.shape()[1] == 3;

Resize
|
||
|
|
--------
|
||
|
|
|

|
||
|
|
|
||
|
|
* **Synopsis**:
|
||
|
|
|
||
|
|
.. cpp:function:: void resize(size_t, ..., size_t)
|
||
|
|
|
||
|
|
* **Examples** ::
|
||
|
|
|
||
|
|
array<double,2> A(2,3);
|
||
|
|
A.resize ( make_shape (5,5) )
|
||
|
|
|
||
|
|
matrix<double,2> M;
|
||
|
|
M.resize( 3,3);
|
||
|
|
|
||
|
|
vector<double> V;
|
||
|
|
V.resize(10);
|
||
|
|
|
||
|
|
* Views can not be resized.

.. cpp:function:: void resize_or_check_if_view(ArrayType const & A, shape_t)
|
||
|
|
|
||
|
|
* If A is a value : resize A
|
||
|
|
* If A is a view : check that the shape if the shape_t and throw an exception if not.
