Shape & dimensions

==================================

|
|
**Synopsis**:
|
|
|
|
.. code-block:: c
|
|
|
|
template <ImmutableArray A> mini_vector<size_t,R> get_shape(A const &); // R is the rank of A
|
|
|
|
template<ImmutableArray A> size_t first_dim (A const & x);
|
|
template<ImmutableArray A> size_t second_dim (A const & x);
|
|
template<ImmutableArray A> size_t third_dim (A const & x);
|
|
template<ImmutableArray A> size_t fourth_dim (A const & x);
|
|
template<ImmutableArray A> size_t fifth_dim (A const & x);
|
|
template<ImmutableArray A> size_t sixth_dim (A const & x);
|
|
template<ImmutableArray A> size_t seventh_dim (A const & x);
|
|
|
|
|
|
The shape and dimensions of any object modeling :ref:`ImmutableCuboidArray` is obtained using get_shape and xxx_dim functions :
|
|
|
|
.. compileblock::
|
|
|
|
#include <triqs/arrays.hpp>
|
|
#include <iostream>
|
|
using namespace triqs::arrays;
|
|
int main () {
|
|
auto a = array<double,2> (2,3);
|
|
std::cout << get_shape(a)<< std::endl;
|
|
std::cout << first_dim(a)<< std::endl;
|
|
std::cout << second_dim(a)<< std::endl;
|
|
}
