Can a Matrix A Equalize Vectors u and v in Different Reference Frames?

Click For Summary
SUMMARY

The discussion centers on the mathematical relationship between two vectors, u and v, defined in different reference frames within a vector space. A matrix A can equalize these vectors if it is a non-singular n by n matrix, where n represents the dimension of the vector space. The columns of matrix A consist of coefficients that express vector u as a linear combination of vector v. The challenge arises from the fact that u and v are not defined in the same reference frame, complicating the transformation process.

Hi everyone,

Given two different reference frames in a vector space; say left and right. v is a vector defined in the left frame and u is a vector defined in the right frame.
What is the nature of a matrix A that can satisfy the equality u= A.v?
Thank you

If the vector space has dimension n, then A is represented by the n by n, non-singular, matrix whose columns are the coefficients of vectors in u when written as a linear combination of the vectors in v.
 
Thanks HallsofIvy,
the problem is that the two vectors u and v are not defined in the same reference frame.
