FORbID, FORtran Integral Definite solver

  • FORbID is a pure Fortran (KISS) library for numerical integration of definite integrals;
  • FORbID is Fortran 2008+ standard compliant;
  • FORbID is OOP designed;
  • FORbID is a Free, Open Source Project.

What is FORbID?

With modern Fortran standards (2003+) introduction, is possible to develop a KISS and lightweight library for numerical integration of definite integrals using the new features of Object Oriented Programming like Abstract Data Type (ADT).

Main features

FORbID is aimed to be a KISS-pure-Fortran library for numerical integration of definite integrals.

  • Pure Fortran implementation;
  • KISS and user-friendly:
    • simple API, presently based on the Rouson's Abstract Data Type Pattern [2];
    • easy building and porting on heterogeneous architectures;
  • comprehensive integrators set out-of-the-box [1]:
    • Newton-Cotes interpolation formulas;
      • trapezoidal rule;
      • Cavalieri-Simpson's rule;
      • Cavalieri-Simpson's 3/8 rule;
      • Boole's rule;
      • Newton-Cotes' 6 points rule;
      • Newton-Cotes' 7 points rule;
      • Newton-Cotes' 8 points rule;
      • Newton-Cotes' 9 points rule;
      • Newton-Cotes' 10 points rule;
      • Newton-Cotes' 11 points rule;
      • Romberg's method.
    • Gaussian quadrature formulae:
      • Gauss-Legendre formula;
      • Gauss-Kronrod formula;
      • Gauss-Chebyshev formula;
      • Montecarlo schemes for multidimensional function;
      • acceleration methods;
    • Integration formulas of interpolatory type:
      • Fejér interpolation formula;
      • Clenshaw-Curtis interpolation formula;
    • Adaptive quadrature
      • Adaptive Newton-Cotes integration;
      • Adaptive Gaussian integration;
  • efficient:
    • high scalability on parallel architectures:
      • support for shared memory multi/many cores architecture;
      • support for distributed memory cluster;
  • Tests-Driven Developed (TDD):
  • well documented:
    • clear documentation of schemes implementations;
    • comprehensive wiki:
  • collaborative developed on GitHub;
  • FOSS licensed;

Any feature request is welcome.
