A cbind/rbind for tensors

Tensors can be put side by side in one dimension if they are of equal size in all other dimensions.

bind.tensor(A,dA=NULL,B,dB=dA)

Arguments

A

the first tensor

dA

the dimension of A to be used for binding the tensors

B

the second tensor

dB

the dimension of B to be used for binding the tensors

Value

a tensor with the tensors combined to one

Details

This function works like a cbind or rbind function for tensors.

Note

binding does not preserve the sequence of the dimensions.
