C-Library & Matlab Toolbox implement a numerical solution of Poisson equationdiv(e*grad(u))=fin 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 parametersMATLAB VERSION: 6.5 - 7.9FILES:C-LIBRARY:COMMON.C, COMMON.H - data types, memory managementPSN_3D.C, PSN_3D.H - 3D Poisson solverMATLAB TOOLBOX 3D:PSN_3D_MEX.C - POISSON 3D MATLAB MEX SOURCEPSN_3D_MAKE.M - MAKE MEX-DLL SCRIPTPSN_3D_DEMO.M - POISSON 3D DEMO, CARTESIAN COORDINATESFAST START:1.
