		For 2D arrays (and higher dimensions), you can specify the dimension along which
		the cumulative sum will be performed. If none is specified, it will be performed


		For 2D arrays (and higher dimensions), you can specify the dimension along which
		the cumulative sum will be performed. If none is specified, it will be performed
		along the first dimension (0):

		\param[in] in is the input array
		\param[in] dim The dimension along which exclusive sum is performed
		\return the output containing exclusive sums of the input
		\param[in] dim is the dimension along which inclusive sum is performed

		\param[out] out will contain inclusive sums of the input
		\param[in] in is the input array
		\param[in] dim The dimension along which exclusive sum is performed
		\param[in] dim is the dimension along which inclusive sum is performed
