modeSum: Tensor Sum Across Single Mode of DelayedArray

In rikenbit/DelayedTensor: R package for sparse and out-of-core arithmetic and decomposition of Tensor

Tensor Sum Across Single Mode of DelayedArray

Description

Given a mode for a K-tensor, this returns the K-1 tensor resulting from summing across that particular mode.

Usage

modeSum(darr, m = NULL, drop = FALSE)

## S4 method for signature 'DelayedArray'
modeSum(darr, m, drop)

Arguments

darr	DelayedArray object
m	the index of the mode to sum across
drop	whether or not mode m should be dropped

Details

This function is an extension of the modeSum by DelayedArray.

NOTE: Sparse mode of modeSum is not available for now.

modeSum(darr, m=NULL, drop=FALSE)

Value

K-1 or K tensor, where K = length(dim(darr))

Examples

library("DelayedRandomArray")
darr <- RandomUnifArray(c(1,2,3))
modeSum(darr, 1, drop=FALSE)
modeSum(darr, 1, drop=TRUE)
modeSum(darr, 2)
modeSum(darr, 3)
