einops-style multi dimensional meshgrids

Installation

Simple installation from pip:

pip install einmesh

API

Create high dimensional meshgrids through a single command.

from einmesh import einmesh, LogSpace, LinSpace

x, y = einmesh(
    "x y",                                       # Name a set of axis einops style
    x=LinSpace(start=0, end=3, num=3),           # Provide a space to sample from
    y=LogSpace(start=0, end=1, num=3, base=10),  # -- Mix and match as you like!
)
print(f"{x=}")
print(f"{y=}")

Will output

x=tensor([[0.0000, 0.0000, 0.0000],
        [1.5000, 1.5000, 1.5000],
        [3.0000, 3.0000, 3.0000]])
y=tensor([[ 1.0000,  3.1623, 10.0000],
        [ 1.0000,  3.1623, 10.0000],
        [ 1.0000,  3.1623, 10.0000]])

Thus it is effectively equivalent to common torch code

x = torch.linspace(start=0, end=1, num=3)
y = torch.logspace(start=0, end=1, num=3, base=10)

x, y = torch.meshgrid(x, y, indexing="ij")

Which in 2D is not too bad, but in high dimensions can get tireing!
