modeSum-methods: Tensor Sum Across Single Mode

In jamesyili/rTensor: Tools for tensor analysis and decomposition

Description

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

Usage

modeSum(tnsr, m, drop)

## S4 method for signature 'Tensor'
modeSum(tnsr, m = NULL, drop = FALSE)

Arguments

tnsr	the Tensor instance
m	the index of the mode to sum across
drop	whether or not mode m should be dropped

Details

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

Value

K-1 or K tensor, where K = x@num_modes

See Also

modeMean

Examples

tnsr <- rand_tensor()
modeSum(tnsr,3,drop=TRUE)
