%@info:
%! @deftypefn {Function File} internals (@var{flag},@var{a},@var{b}, ...)
%! @anchor{internals}
%! @sp 1
%! This command provides internal documentation and unitary tests for the matlab routines.
%! @sp 2
%! @strong{Inputs}
%! @sp 1
%! @table @ @var
%! @item flag
%! Mandatory argument: --doc (for displaying internal documentation) or --test (for performing unitary tests).
%! @item b
%! Name of the routine to be tested or for which internal documentation is needed.
%! @item c
%! Name of the routine to be tested.
%! @item d
%! @end table
%! @sp 1
%! @strong{Outputs}
%! @sp 1
%! None.
%! @sp 2
%! @strong{Examples}
%! @sp 1
%! The following instruction:
%! @sp 1
%! @example
%! internals --info particle/local_state_iteration
%! @end example
%! will display the internal documentation of the routine local_state_iteration located in the particle subfolder of the matlab directory.
%! @sp 1
%! The following instruction:
%! @sp 1
%! @example
%! internals --test particle/local_state_iteration
%! @end example
%! will execute the unitary tests associated the routine local_state_iteration.
%! @sp 2
%! @strong{Remarks}
%! @sp 1
%! [1] It is not possible to display the internal documentation of more than one routine.
%! @sp 1
%! [2] It is possible to perform unitary tests on a list of routines.
%! @sp 1
%! [3] For displaying the internal documentation, matlab calls texinfo which has to be installed.
%! @sp 2
%! @strong{This function is called by:}
%! @sp 2
%! None.
%! @sp 2
%! @strong{This function calls:}
