Prev:	transpose ( tensor: tensor -- tensor': tensor )
Next:	hstack ( seq -- tensor )

Vocabulary
tensors

Inputs

seq	a sequence

Outputs

tensor

a tensor

Word description
Joins the sequences in seq along a new axis. tensor will have one more dimension than the arrays in seq.

Errors
Throws a shape-mismatch-error if the sequences in seq do not have the same shape.
