Concatenates tensors along one dimension.

concat_dim A Tensor of type int32. 0-D. The dimension along which to concatenate. Must be in the range [0, rank(values)).
values A list of at least 2 Tensor objects with the same type. The N Tensors to concatenate. Their ranks and types must match, and their sizes must match in all dimensions except concat_dim.
name A name for the operation (optional).

A Tensor. Has the same type as values.
