%#
%# OdePkg is part of the GNU Octave Repository (the Octave--Forge project). The package includes commands for setting up various options, output functions etc. before solving a set of differential equations with the solver functions that are also included. At this time OdePkg is under development with the main target to make a package that is mostly compatible to proprietary solver products.
%#
%# If this function is called without any input argument then open the OdePkg tutorial in the Octave window. The tutorial can also be opened with the following command
%#
%# @example
%# doc odepkg
%# @end example
%# @end deftypefn

  %# Check number and types of all input arguments
