[ cos(phi)*cos(theta), -sin(theta), -cos(theta)*sin(phi)]= 1
[ cos(phi)*sin(theta), cos(theta), -sin(phi)*sin(theta)]=0
[ sin(phi), 0, cos(phi)]=0
How to solve the phi and theta?
I tried A\B, it seems don't work.
Thanks,

As you have posed it, your question does not make sense. You are setting three-element row vectors equal to scalars. What are the actual equations you are trying to solve? There are two unknowns, so presumably you have two equations in mind.

Actually, I have a vector i,j,k. I want to multiply it with a rotational matrix to make the vector align with one of the three axis(x,y,z)
