ttt: Inner product of tensor X and Y

In kusakehan/TEReg: An R package for tensor envelope regression with tensor response and tensor predictor

Description

ttt(X,Y,dims) computes the inner product of tensors X and Y in the dimensions specified by the vector dims. The sizes of the dimensions specified by dims must match, which is size(X, dims) must equal size(Y, dims).

Usage

ttt(X, Y, dims)

Arguments

X	A tensor instance.
Y	A tensor instance.
dims	The indices of the modes to map onto the column space.

Value

mat	The inner product of tensors X and Y in the dimensions specified by the vector dims, which is a matrix.

Examples

 X = as.tensor(array(runif(24), c(3, 4, 2)));
 Y = as.tensor(array(runif(24), c(3, 4, 2)));
 Z = ttt(X, Y, 1:2)
