<A NAME="MatCreateMAIJ"><H1>MatCreateMAIJ</H1></A>
Creates a matrix type providing restriction and interpolation operations for multicomponent problems. It interpolates each component the same way independently. The matrix type is based on <A HREF="../Mat/MATSEQAIJ.html#MATSEQAIJ">MATSEQAIJ</A> for sequential matrices, and <A HREF="../Mat/MATMPIAIJ.html#MATMPIAIJ">MATMPIAIJ</A> for distributed matrices.
