X-Complaints-To: abuse@twtelecom.net Xref: csiph.com comp.soft-sys.math.mathematica:16574 I have a function f[x] which I want to minimize, but its rather involved, it will return a number for a numerical x, but if x is symbolic, it's not going to happen. Trying to use NMinimize, I get errors that are consistent with NMinimize calling f[] with a symbolic argument. Is there something simple I am doing wrong?
