Very simple question relating to symbolic matrix rotations

I used syms to represent three variables in three 3x3 matrices. I performed linear algebra to obtain a single 3x3 matrix. I now need to assign numerical values to the three symbolic variables, so that I can make use of the single 3x3 transformation matrix I made. How do I convert a symbolic variable to a variable that represents a numerical value?
