<A HREF="../Mat/MATLUSOL.html#MATLUSOL">MATLUSOL</A> = "lusol" - A matrix type providing direct solvers (LU) for sequential matrices via the external package LUSOL. If LUSOL is installed (see the manual for
instructions on how to declare the existence of external packages),
a matrix type can be constructed which invokes LUSOL solvers.
After calling <A HREF="../Mat/MatCreate.html#MatCreate">MatCreate</A>(...,A), simply call <A HREF="../Mat/MatSetType.html#MatSetType">MatSetType</A>(A,<A HREF="../Mat/MATLUSOL.html#MATLUSOL">MATLUSOL</A>).
This matrix type is only supported for double precision real.
<P>
This matrix inherits from <A HREF="../Mat/MATSEQAIJ.html#MATSEQAIJ">MATSEQAIJ</A>. As a result, <A HREF="../Mat/MatSeqAIJSetPreallocation.html#MatSeqAIJSetPreallocation">MatSeqAIJSetPreallocation</A> is
supported for this matrix type. <A HREF="../Mat/MatConvert.html#MatConvert">MatConvert</A> can be called for a fast inplace conversion
to and from the <A HREF="../Mat/MATSEQAIJ.html#MATSEQAIJ">MATSEQAIJ</A> matrix type.
