Maximum absolute value of a coefficient function

Hi, can anyone suggest a clever way to compute the maximum absolute value of a coefficient function over a mesh? I can work it out by evaluating the coefficient function at mapped integration points and using Numpy, but maybe there is a better way...

Thanks,

Hi,
Did you see the possibility of using mesh points in an numpy array (and evaluating cfs quickly on them)?
I described that in this thread:
