Mexcgns - MEX interface of CGNS for MATLAB and Octave

MexCGNS is an interface of CGNS for MATLAB and Octave through MATLAB Executables (MEX). CGNS CGNS is a de facto standard file format for exchanging data in CFD and other mesh-based simulations. It provides native C and Fortran interfaces. However, many users and developers in scientific and engineering computing use MATLAB and Octave for daily development work. MexCGNS provides the complete CGNS mid-level library interface to users through MEX functions. MexCGNS also provides some high-level int


CGNS++ is an object oriented interface to provide access to CGNS (CFD General Notation System) databases. It is similar to the existing C and FORTRAN interfaces provided by, but uses an object oriented abstraction of the underlying SIDS.
