hello,
i have a problem. if i know that
where and are scalars and and are matrices,
does this mean that ?
also, is diagonal, if that helps.
cheers for reading and sorry if this is a dumb question,
jack.

Look at the 2x2 case. Assuming a=1 then we need to solve the equation
(b-1)(n(p+bm+m)+sm) = 0 where p is the top left coordinate of the matrix K, s the bottom left. m, n are the coordinates of M. Assuming b is not 1 then we want to find n, m, b, p, s such that n(p+bm+m)+sm=0. So, let s=0=n.
That is, and
is a counter-example.
