rTensor (version 1.4.8)

modeSum-methods: Tensor Sum Across Single Mode

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 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

Value

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

Details

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

Examples

# NOT RUN {
tnsr <- rand_tensor()
modeSum(tnsr,3,drop=TRUE)
# }
