Any orthnormal matrix can keep the curve's shape and size unchnaged?
Dear R users,
I want to know, given a curve f in d-dimensional space,
It is possible to keep the curve’s shape and size unchanged by
an arbitrary dxd orthnormal matrix A?
That is, the new curve g = A*f is still the same shape and size as f?
Thanks for your advices and answers.
