xexpand_dims_view

Defined in xframe/xexpand_dims_view.hpp

template<class CT>
class xexpand_dims_view : public xt::xexpression<xexpand_dims_view<CT>>, private xf::xvariable_base<xexpand_dims_view<CT>>

View on a variable with additional axes.

The xvariable_masked_view class is used for creating a view on a variable with additional axes.

Template Parameters

• CT: the closure type on the underlying variable.

Public Functions

template<class E>
xexpand_dims_view(E &&e, const extra_dimensions_type &dims)

Constructs an xexpand_dims_view given a map of extra dimensions.

Parameters

• e: the variable expression on which to create the view.

• dims: the map of extra dimensions, the key being the dimension name, the value the position where to put the new dimension.

template<class E, class K>
auto xf::expand_dims(E &&e, std::initializer_list<K> dim_names)

Creates a view on a variable expression with additional axes, given a list of extra dimension names.

Parameters

• e: the variable expression on which to create the view.

• dim_names: the list of extra dimension names.

template<class E>
auto xf::expand_dims(E &&e, std::initializer_list<std::pair<typename std::decay_t<E>::key_type, std::size_t>> dims)

Creates a view on a variable expression with additional axes, given a list of extra dimensions.

Parameters

• e: the variable expression on which to create the view.

• dims: the extra dimensions as a mapping “dimension name” -> “position”.
