If this matrix is set, <A HREF="../ST/STApply.html#STApply">STApply</A> will effectively apply D*OP*D^{-1}. Use NULL
to reset a previously passed D.
<P>
Balancing is usually set via <A HREF="../EPS/EPSSetBalance.html#EPSSetBalance">EPSSetBalance</A>, but the advanced user may use
this function to bypass the usual balancing methods.
