Not exactly what you asked, but something that you may consider: GoMLX <https://github.com/gomlx/gomlx>. It's an accelerated ML and Math library that uses XLA <https://github.com/openxla/xla> --> it just-in-time compiles a computation graph to CPU/GPU (and hopefully soon TPU). It powers Jax/Tensorflow and is really fast (after the first execution).
Now, while pretty rich set of functionality, it's not a super-set of Gonum (it has some stuff not available in Gonum also). If anything is missing, but is supported by XLA <https://www.tensorflow.org/xla/operation_semantics>, I would be happy to add. Plus it's well documented (see tutorial <https://github.com/gomlx/gomlx/blob/main/examples/tutorial/tutorial.ipynb>). Storage is row-major for 2d-tensors by default -- but internally it may reshuffle storage depending on optimization. ps.: It's a biased suggestion (plus a bit of advertisement) because I created the project.
