Hi,
I have a data structure e.g. {a,{b,c},{d,{e,f},{g}}}, which I want to check
for NumericQ. For vectors and matrices I can use VectorQ[x,NumericQ] or
MatrixQ[x,NumericQ]. Is there a way to check an arbitrary data structure
that all elements are NumericQ or I have to construct a function for each
data structure?
Thanks in advance,
--Ted
