Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a basic question on Mueller matrix which I came across upon reading through the Handbook of Optic, chapter 22 polarimetry. It says that :-

when a polarization element with Mueller matrix M is rotated about the beam of light by an angle \theta such that the angle of incident is unchanged, the resulting Mueller matrix M is :

= M(\theta)

= R(\theta) M R(-\theta)

= [matrix elements of R(\theta)] [matrix elements of M] X [matrix elements of R(-theta)]

My question is, what does the "X" mean here..

From my reading, the cross product is used with vector. This time, it's a matrix.

Sorry if this is too basic, I've just started brushing up my matrix since college.

Appreciate any help.

regards,
