Syms and Plugging numbers into equations

Essentially I used syms so that I could do a partial derivative, g. Now that I have that, I want to plug in the values for the symbols I created, and then plug those values into g, and have MATLAB return a numerical result as my final answer.

How would I go about doing this?

double( subs(g, {variable1, variable, variable3, ..), {value1, value2, value3, ...}) )
