Is it possible to do dot product on a vector with matrices in D3DX9?

I am trying to convert this project into C++ equivalence...

https://github.com/unr-arl/DubinsAirplane

In the python code

np.dot(rotz(pi/2), np.array([cos(anglstart), sin(anglstart), 0]).T)

It is trying to compute the dot product of a rotation matrix around z axis and dot with

a column vector...

The D3DXVec3Dot only works with dotting two vectors together?

Thanks

Jack
