<A NAME="MatCreateSeqDense"><H1>MatCreateSeqDense</H1></A>
Creates a sequential dense matrix that is stored in column major order (the usual Fortran 77 manner). Many of the matrix operations use the BLAS and LAPACK routines.

<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
The data input variable is intended primarily for Fortran programmers
who wish to allocate their own matrix memory space. Most users should
set data=NULL.
