Questions 11

1. Consider our lectures/10 example with the root function. How can you find out the declaration of the gsl_multiroot_fsolver structure which is used in root.c ?

   Hint (explain): gcc -E -P root.c | grep -B8 'gsl_multiroot_fsolver;'

2. Find out the declaration of the gsl_multimin_fminimizer structure.
3. During the multiroot iteration loop, how can you find out the current approximation to the root and the values of the to-be-zeroed-functions at this point?
4. During the multimin iteration loop, how can you find out the current approximation to the minimum and the value of the to-be-minimized-function at this point?
