Euler-Lagrange eqn. 4.2 can be written as

where μj∏(= ∑2j=i∕zj) is the bulk chemical potential of the chain. Rearranging
eqn. 4.30 gives
pj∙(r) = exp(∕3μ⅛f) exp[Pj∙(r) - /3V∕rf(r)]∕1 j(r)∕2,√r). (4.31)

Picard-type iteration method is used to solve the set of eqs. 4.31 for the density
profile of the segments. For the systems considered in this work, the inhomogeneity is
only in one dimension (z). For the density profile, a grid is set up in the z dimension
