<A HREF="../Mat/MATMATLAB.html#MATMATLAB">MATMATLAB</A> = "matlab" - A matrix type providing direct solvers (LU and QR) and drop tolerance based ILU factorization (ILUDT) for sequential matrices via the external package Matlab. If Matlab is instaled (see the manual for
instructions on how to declare the existence of external packages),
a matrix type can be constructed which invokes Matlab 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/MATMATLAB.html#MATMATLAB">MATMATLAB</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. One can also call <A HREF="../Mat/MatConvert.html#MatConvert">MatConvert</A> for an inplace conversion to or from
the <A HREF="../Mat/MATSEQAIJ.html#MATSEQAIJ">MATSEQAIJ</A> type without data copy.
