Homework Assignment # 4

(Due Thursday, March 2 at 8:40 am in Lab.)

Agenda and readings for the week of February 1:

All readings from Numerical Recipes: The Art of Scientific Computing, 2 edition (in Fortran or C).

• Lec8, 02/29: Interpolation; Solution of many non-linear equations in many unknowns (Broyden approaches)
  Reading: 9.6-9.7
• Lab3, 03/02: Full atomic spectra for periodic table (one-electron atoms)

Goal: This homework develops a fully automated solver which finds all of the energy states for any specified external potential ``V[]''.
