ReduceSubarraysSumCPU()

template<class T >

void open3d::ml::detail::ReduceSubarraysSumCPU	(	const T *const	values,
		const size_t	values_size,
		const int64_t *const	prefix_sum,
		const size_t	prefix_sum_size,
		T *	out_sums
	)

Reduces subarrays in linear memory with the sum operation. The sum for empty subarrays is 0.

Parameters

values	The linear array with all values
values_size	Number of elements of values
prefix_sum	The exclusive prefix sum of the number of elements for each array
prefix_sum_size	The number of subarrays
out_sums	The preallocated output array with size prefix_sum_size
