## @deftypefn {Function File} @var{str} = poointGeo (@var{n}, @var{xyz}, @var{l})
## Generates a string for Gmsh Point format.
##
## Gmsh's simplest `elementary entity', a `Point'. A Point is defined by a list
## of five numbers: @var{n} the identificator, @var{xyz} three coordinates (X, Y
## and Z), and a characteristic length @var{l} that sets the target element size
## at the point:
## The distribution of the mesh element sizes is then obtained by
## interpolation of these characteristic lengths throughout the
## geometry.
##
## @end deftypefn
function str = pointGeo(n,xyz,l)
str = sprintf('Point(%d) = {%.16g,%.16g,%.16g,%.16g};\n',n,xyz,l);
end
