Band matrix conjugation relation between orthogonal matrices












0












$begingroup$


Suppose I have two orthogonal matrices:
$C_1,C_2$ of some dimension $n$.



It is given that



$C_2 = R_1*C_1*R_2$



where R1,R2 are orthogonal matrices as well.



How can I solve for $R_1$ and $R_2$ when $C_1,C_2$ are given?



Additionally, if it is given that $R_1$ and $R_2$ are band matrices,
do I have a way to promote a solution, such that $R_1$ and $R_2$ will be band matrices?
