This returns a flattened xtensor with the sorted, unique values in ar1 that are not in ar2. Inline auto setdiff1d ( const xexpression & ar1, const xexpression & ar2 ) ¶įind the set difference of two xexpressions. ParametersĮ – input xexpression (will be flattened) template This returns a flattened xtensor with sorted, unique elements from the original expression. Inline auto unique ( const xexpression & e ) ¶ Returns xarray with positions of maximal value template ![]() If axis is specified, the indices are along the specified axis. Inline auto argmax ( const xexpression & e, std :: ptrdiff_t axis ) ¶įind position of maximal value in xexpression By default, the returned index is into the flattened array. If not set, computes the median along a flattened version of the input. ParametersĪxis – axis along which the medians are computed. Given a vector V of length N, the median of V is the middle value of a sorted copy of V, V_sorted - i e., V_sorted, when N is odd, and the average of the two middle values of V_sorted when N is even.

Xt::quantile(E& e, P const& probas, std::ptrdiff_t axis, xt::quantile_method method) template The algorithm partially sorts entries in a copy along the axis axis. When the cutpoint falls between two elemnts of the sample distribution, a interpolation is computed using the alpha and beta coefficients, as descripted in (Hyndman and Fan, 1996). In a sorted array represneting a distribution of numbers, the quantile of a probability p is the the cut value q such that a fraction p of the distribution is lesser or equal to q. Inline auto quantile ( E & & e, const P & probas, std :: ptrdiff_t axis, T alpha, T beta ) ¶ This function uses std::nth_element internally. The optional third parameter can either be an axis or xnone() in which case the xexpression will be flattened. Partition shuffles the xexpression in a way so that the kth element in the returned xexpression is in the place it would appear in a sorted array and all elements smaller than this entry are placed (unsorted) before. Inline R partition ( const xexpression & e, C kth_container, placeholders :: xtuph ) ¶ ParametersĪxis – axis along which argsort is performedĪrgsorted index array template, class = std :: enable_if_t :: value, int > ![]() Returns an xarray of indices of the same shape as e that index data along the given axis in sorted order. Inline auto argsort ( const xexpression & e, std :: ptrdiff_t axis = - 1 ) ¶Īrgsort xexpression (optionally along axis) Performs an indirect sort along the given axis. ParametersĪxis – axis along which sort is performed Sort xexpression (optionally along axis) The sort is performed using the std::sort functions.Ī copy of the xexpression is created and returned. Inline auto sort ( const xexpression & e, std :: ptrdiff_t axis = - 1 ) ¶
