Help needed with partial differentiation equation of matrices

With reference to Eq. 16 in the attachment, I need help in understanding how the working is done to obtain the answers in Eq. 17.

Eqs. 10, 11, and 15 are the inputs needed to solve Eg. 16.

I am puzzled how a matrix could be differentiated with respect to another matrix. I would highly appreciate it if an example calculation can be shown. Thanks in advance!

From the results,I see that is dot product,not differentiation

$\displaystyle R_{i\_st}=\sum_{k=1}^3 R_k (v_k\cdot v_{i\_st})$
