What kind of non-differentiable you have in mind (could you give a
typical example of a function)?
Numerical method or symbolic?
May be:
1) try to use left and right derivatives
2) investigate sign of the difference f(x+h)-f(x)
3) investigate the domain of the derivative (for example: if f(x)=abs(x)
then we have diff(f(x),x)=x/abs(x))
