<P>
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
The i, j, and a arrays are not copied by this routine, the user must free these arrays
once the matrix is destroyed
<P>
You cannot set new nonzero locations into this matrix, that will generate an error.
<P>
The i and j indices are 0 based
<P>
When block size is greater than 1 the matrix values must be stored using the SBAIJ storage format (see the SBAIJ code to determine this). For block size of 1
it is the regular CSR format excluding the lower triangular elements.
