  • Finalize design:
    • permutedims
    • inv
    • cov/cor
      • dims= 1/2
      • Any other dimension gives a diagonal with NaNs. The solution right now uses the same method for diag (described below) but then uses that axis for the first and second axes of the returned matrix.
    • Matrix multiplication
    • diag: the current solution is equivalent to promoting both axes (promote(axes(m)...)) and returning the shortest one (kind of like the rank axis).
  • Document axis interface
  • Document customization with axes
  • Examples with AbstractAxisIndices

Most of these are very straightforward. I feel like the current solution for the deriving the axis that corresponds to the diagonal is pretty good but I'm not as set on it as the others.

v0.2.0 consolidated inverse_axes into permute_axes. Doesn't change behavior just simplifies code.
