Concatenate Tensors

Concatenate two 2D tensors along a specified axis.

Input:

• a: A 2D tensor
• b: A 2D tensor
• axis: The axis along which to concatenate (0 for rows, 1 for columns)

Output: The concatenated tensor.

API Reference:

• PyTorch: torch.cat([a, b], dim=axis)
• JAX: jnp.concatenate([a, b], axis=axis)
