Detailed Description

Function Documentation

cumprod()

template<class T = void, class E >

auto xt::cumprod ( E && e, std::ptrdiff_t axis )

inline

Cumulative product.

Returns the accumulated product for the elements over given axis (or flattened).

Parameters

e	an xexpression
axis	the axes along which the cumulative product is computed (optional)

Template Parameters

T	the value type used for internal computation. The default is E::value_type. Tis also used for determining the value type of the result, which is the type of T() * E::value_type(). You can pass big_promote_value_type_t<E> to avoid overflow in computation.

Returns

an xarray<T>

cumsum()

template<class T = void, class E >

auto xt::cumsum ( E && e, std::ptrdiff_t axis )

inline

Cumulative sum.

Returns the accumulated sum for the elements over given axis (or flattened).

Parameters

e	an xexpression
axis	the axes along which the cumulative sum is computed (optional)

Template Parameters

T	the value type used for internal computation. The default is E::value_type. Tis also used for determining the value type of the result, which is the type of T() + E::value_type(). You can pass big_promote_value_type_t<E> to avoid overflow in computation.

Returns

an xarray<T>
