Computes the generalized product (outer, inner, or contracted) of two tensors.
Usage
ttt(tensorA, tensorB, dimsA = NULL, dimsB = dimsA)
Arguments
- tensorA
A Tensor object
- tensorB
A Tensor object
- dimsA
Subscripts of the dimensions in tensorA to contract over.
- dimsB
Subscripts of the dimensions in tensorB to contract over. Defaults to dimsA.
Value
A new Tensor object representing the product.
Details
If dimsA and dimsB are NULL, computes the outer product.
If dimsA and dimsB are provided, computes the contracted product along the specified dimensions.
The sizes of the corresponding dimensions must match.
Examples
t1 <- tensor(array(1:24, dim = c(4, 3, 2)))
t2 <- tensor(array(1:12, dim = c(3, 2, 2)))
# Outer product
result_outer <- ttt(t1, t2)
# Contract over dimensions
result_contracted <- ttt(t1, t2, dimsA = c(2, 3), dimsB = c(1, 2))
