摘要: The BVPh (version 1.0) is a Mathematica package for highly nonlinear boundary-value/eigenvalue problems with singularity and/or multipoint boundary conditions. It combination of the homotopy analysis method (HAM) and computer algebra system Mathematica, provides us convenient analytic tool to solve many ordinary differential equations (ODEs) even some partial (PDEs). In this chapter, we briefly describe its scope, basic mathematical formulas, choice base functions, initial guess auxiliary linear operator, so on, together simple users guide. As open resource, 1.0 given in appendix chapter free available (Accessed 25 Nov 2011, will be updated future) at http://numericaltank.sjtu.edu.cn/BVPh.htm
