can this construction with the column_stack with a tuple than be used to make an @parallel decorator? (

by "@parallel decorator", I assume you refer to the IPython parallel setup, which I've never used. This looks like a case that would work for it. My answer is already parallel using multiprocessing, but you could look into the ipython solution as well.

No, by the @parallel, i mean just a decorator that is general in use, and that executes in parallel whatever function you use it on, (could be useful for image processing or stuff that massively uses ndarrays for simulations etc-

@usethedeathstar As far as I know there is no general use parallel decorator, as there are several different ways to implement parallelism in python, some of which use threads, some use processes, and therefore have different handling of the GIL. The decorator I was referring to is the one provided by IPython's parallel construct but I don't believe it can be used outside of IPython. Using numpy instead of builtins like zip will also run parallel

like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
