My professor wrote a paper about tennis a couple of years ago and he's asked us to recreate some of his results. So I have this vector:

I'm supposed to multiply it with this matrix:

to get (p1, 0, 0, 0, q1).

p1 is:

q1 is similar but the p's and q's are switched around.

2. Relevant equations

This is the paper my teacher wrote and from which the above screenshots came from: http://www.math-cs.ucmo.edu/~mjms/2001.3/Yliuten.pdf [Broken]

3. The attempt at a solution

I have tried and tried and tried to multiply this vector and matrix and, while I get the same answer every time, it does not look anything like p1 or q1.

This is what I get:

I had a friend do it for me and he got the same answer too. So maybe I didn't read the paper carefully enough?
