modeSum-methods

Tensor Sum Across Single Mode

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

modeSum(tnsr, m, drop)

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

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

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

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

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