This is so important! I spend my life writing EKFs for navigation systems however did not have a good linear algebra education. It was a hard struggle! Now, every time I have a new hire or intern, the first thing that I go over is basic linear algebra and rotations including DCM, Euler angles, quaternions, and so on. I also make sure they understand it graphically such as how you can scale and project vectors using a matrix.
