C-Library & Matlab Toolbox implement a numerical solution of Poisson equation div(e*grad(u))=f in Cartesizan 3D coordinates with respect to steeply varying dielectrical permittivity e. Library uses regular rectangular grid with mixed boundary conditions, FVM-based equation discretization and iterative methods for solving sparse linear system. The solver can accommodate the severe jumps in dielectric permittivity typical of ion channels (d?TA=80 and d?TA=2 respectively for water and protein) and includes a Poisson-Boltzmann (PB) extension providing a solution of the linearized PB equation. The solver has been designed to calculate forces and potentials for single/multiple charges in model ion channel model with different parameters MATLAB VERSION: 6.
