As a quick demo:

```python
import numpy as np
import xyzpy as xyz

def some_function(x, y, z):
    return x * np.random.randn(3, 4) + y / z

# Define how to label the function's output
runner_opts = {
    'fn': some_function,
    'var_names': ['output'],
    'var_dims': {'output': ['a', 'b']},
    'var_coords': {'a': [10, 20, 30]},
}
runner = xyz.Runner(**runner_opts)

# set the parameters we want to explore (combos <-> cartesian product)
combos = {
    'x': np.linspace(1, 2, 11),
    'y': np.linspace(2, 3, 21),
    'z': np.linspace(4, 5, 31),
}

# run them
runner.run_combos(combos)
```

Should produce:

And there are options for [merging successive, disjoint sets of data](http://xyzpy.readthedocs.io/en/latest/generate.html#aggregating-data-harvester) (``combos2, combos3, ...``) and [parallelizing/distributing the work](http://xyzpy.readthedocs.io/en/latest/gen_parallel.html).

There are also multiple ways to define functions inputs/outputs (the easiest of which is just to actually return a ``xr.Dataset``), but do let me know if your use case is beyond them or unclear.","{""total_count"": 1, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 1, ""rocket"": 0, ""eyes"": 0}",,297560256
