classxaxis_function
: public xt::xexpression<xaxis_function<F, R, CT...>>¶ An expression of xaxis.
The xaxis_function class is used for creating an expression on named axis, e.g.
auto expr = not_equal(axis1, 2) && axis2 < 2

autooperator()
(const selector_sequence_type<N> &selector) const¶ Returns an evaluation of the xaxis_function.
Example:
auto axis1 = named_axis("abs", axis(16)); auto axis2 = named_axis("ord", axis({'a', 'c', 'i'})); auto func1 = axis1 < 5 && not_equal(axis2, 'i'); // This will evaluate the xaxis_function for `axis1.label(10) == 9` and `axis2.label(1) == 'c'`` func1({{"abs", 10}, {"ord", 1}});
- Return
the evaluation of the xaxis_function
- Parameters
selector
: a selector_sequence_type for selecting the position where you want to evaluate the function.
