SUMMARY

The P-transformation matrix is essential for converting between different bases in linear algebra. The correct formula for transforming one base into another is determined by the matrix S, where the transformation from basis P to basis Q is represented as S*A*S^-1, and the reverse transformation from basis Q to basis P is represented as S^-1*A*S. Understanding the role of the matrix S is crucial for accurate base conversions.

what is the right formula for the transformation of one base into
another ??

P-transformation matrix

is it S*A*S^-1

or

is it S^-1*A*S

That depends entirely upon what S is!

Obviously, if S*A*S-1 goes from basis P to basis Q, S-1*A*S goes from basis Q to basis P.
