Homework Statement


Given the 2 Matrices, find the transition matrices, Pd to c

d =
[ 1 1 0 ]
[ 0 1 -1 ]
[ 1 1 1 ]

c=
[ 1 0 0 ]
[ 0 1 0 ]
[ 0 0 1 ]

Homework Equations


Pd to c = [d] | [c]

The Attempt at a Solution


Pd to c = [d] | [c]

[ 1 1 0 | 1 0 0 ]
[ 0 1 -1 | 0 1 0 ]
[ 1 1 1 | 0 0 1 ]

The process of getting the transition matrix involves row reducing until we have the identity matrix on the left hand side. The right hand side will then be = the transition matrix.

Transition matrix =

[ 2 -1 -1 ]
[ -1 1 1 ]
[ -1 0 1 ]

Do you have a question?
 
Just checking if I'm doing it correctly. Sorry, I should have stated this in my original post.
 
Have you checked that Pd to c d = c?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
