Matrix invariance

  1. Sep 14, 2007 #1
    I just wanted to know say a matrix X is invariant under some transformation T.

    T:X->Y is invariant...

    does that mean all the elements of X are the same as the elements of Y? Or is the elements in Y a scalar multiple of the elements in X?

    If a matrix (or anything else) is invariant under a transformation T, then T(X)=X. Period.
