With the Lorentz transformation of co-ordinate systems, the way the axes transform relative to one another with different relative velocities looks a lot like a matrix multiplication of a unit square. Can matrices be used in special relativity in this way?

I apologise if my question is a little ambiguous, and would be happy to explain it further

Absolutely! The lorentz transformations can be expressed as four by four matrices that mix up the time and space coordinates. They are part of a largger set of transformations,
which include rotations and translations, known as the poincare group.

Wunderbar! Could you direct me to a website with this delved into differently than wikipedia, which is a little too scary to begin with where Lorentz matrices are concerned?
