gradientFD() [2/2] void pism::inverse::gradientFD ( IPFunctional< array::Vector > &  f, array::Vector &  x, array::Vector &  gradient  ) Computes finite difference approximations of a IPFunctional<array::Vector> gradient. Useful for debugging a hand coded gradient. Definition at line 65 of file IPFunctional.cc.
