nah man. Q is fine. R is the orthogonal matrix i believe. or at least it is always squared
my professor and another solution book both verified my answer.
thanks you guys, but this problem is good

ahh but you are wrong. you have TOO MANY columns. there are only three columns in Q and you just added a row in R to make M work.
i just figure my solution is correct and the soltion book is wrong
Q is
.5 .5 -.5
.5 -.5 .5
.5 -.5 -.5
.5 .5 .5
R is
2 1 2
0 1 -1
0 0 1
that equals M
so i...
your matrices answers seem to big. there should only be three columns in Q
are you sure those are right. i got the answer not the solution and my u1 and u2 are the same as that, but its my u3 that is wrong. it says it is (-3/2, 3/2, 1/2, 1/2)
