I’d like to create a 3d ndarray to represent co-ordinates from three 1d ndarrays similar to how numpy’s meshgrid works. e.g. what is the rust equivalent for python’s:

a = np.array(
    np.meshgrid(
        np.linspace(-1, 1, 50),
        np.linspace(-1, 1, 50),
        np.linspace(-1, 1, 50),
        indexing="ij"
    )
)
