Description

I tried this out:

import Base: \
function \(x::AxisArray{T1, 2}, y::AxisArray{T2, 1}) where {T1, T2}
    x_rows = x.axes[1]
    y_rows = y.axes[1]
    if x_rows == y_rows
        AxisArray(x.data \ y.data, x.axes[2])
    else
        DimensionMismatch("Axes $x_rows and $y_rows don't match")
    end
end

And it seemed to work. I could make a pull request if it seems like a reasonable method?

Research direction

Start by running the AxisArray matrix/vector division example shown in the issue and inspect existing Base method extensions for AxisArray. Confirm the intended axis compatibility and result axes, then add coverage for matching and mismatched axes if the project has a suitable test location. Done means the proposed division behavior is accepted and verified.
