When 
<A HREF=r37_0179.html>solve</A> is applied to a set of equations with multiple r
oots, 
solution multiplicities are normally stored in the global variable 

<A HREF=r37_0017.html>root_multiplicities</A> rather than the solution list. If 
you want 
the multiplicities explicitly displayed, the switch <em>multiplicities</em> 
should be turned on. In this case, <em>root_multiplicities</em> has no value.
