## @deftypefn {Function File} @var{str} = lineLoopGeo (@var{id}, @var{nl}, @var{lns})
## Generates a string for Gmsh Line Loop format.
##
## The third elementary entity is the surface. In order to define a
## simple rectangular surface from defined lines, a
## line loop has first to be defined. A line loop is a list of
## connected lines, a sign being associated with each line (depending
## on the orientation of the line). @var{id} is an indentifier for the loop.
## @var{nl} is the number of lines in the loop. @var{lns} is the list of lines.
##
## @end deftypefn
function str = lineLoopGeo(id,nl,lns)
substr = repmat(',%d',1,nl-1);
str = sprintf(['Line Loop(%d) = {%d' substr '};\n'],id,lns);
