<pre>
-- SuperLU routine (version 2.0) --
Univ. of California Berkeley, Xerox Palo Alto Research Center,
and Lawrence Berkeley National Lab.
November 15, 1997</pre><p>
<pre> Purpose
=======</pre><p>
<pre> Read a FLOAT PRECISION matrix stored in Harwell-Boeing format
as described below.</pre><p>
<pre> Line 1 (A72,A8)
Col. 1 - 72 Title (TITLE)
Col. 73 - 80 Key (KEY)</pre><p>
<pre> Line 2 (5I14)
Col. 1 - 14 Total number of lines excluding header (TOTCRD)
Col. 15 - 28 Number of lines for pointers (PTRCRD)
Col. 29 - 42 Number of lines for row (or variable) indices (INDCRD)
Col. 43 - 56 Number of lines for numerical values (VALCRD)
Col. 57 - 70 Number of lines for right-hand sides (RHSCRD)
(including starting guesses and solution vectors
if present)
(zero indicates no right-hand side data is present)</pre><p>
<pre> Line 3 (A3, 11X, 4I14)
Col. 1 - 3 Matrix type (see below) (MXTYPE)
Col. 15 - 28 Number of rows (or variables) (NROW)
Col. 29 - 42 Number of columns (or elements) (NCOL)
Col. 43 - 56 Number of row (or variable) indices (NNZERO)
(equal to number of entries for assembled matrices)
Col. 57 - 70 Number of elemental matrix entries (NELTVL)
(zero in the case of assembled matrices)
Line 4 (2A16, 2A20)
Col. 1 - 16 Format for pointers (PTRFMT)
Col. 17 - 32 Format for row (or variable) indices (INDFMT)
Col. 33 - 52 Format for numerical values of coefficient matrix (VALFMT)
Col. 53 - 72 Format for numerical values of right-hand sides (RHSFMT)</pre><p>
<pre> Line 5 (A3, 11X, 2I14) Only present if there are right-hand sides present
Col. 1 Right-hand side type:
F for full storage or M for same format as matrix
Col. 2 G if a starting vector(s) (Guess) is supplied. (RHSTYP)
Col. 3 X if an exact solution vector(s) is supplied.
Col. 15 - 28 Number of right-hand sides (NRHS)
Col. 29 - 42 Number of row indices (NRHSIX)
(ignored in case of unassembled matrices)</pre><p>
<pre> The three character type field on line 3 describes the matrix type.
The following table lists the permitted values for each of the three
characters. As an example of the type field, RSA denotes that the matrix
is real, symmetric, and assembled.</pre><p>
<pre> First Character:
R Real matrix
C Complex matrix
P Pattern only (no numerical values supplied)</pre><p>
<pre> Second Character:
S Symmetric
U Unsymmetric
H Hermitian
Z Skew symmetric
R Rectangular</pre><p>
<pre> Third Character:
A Assembled
E Elemental matrices (unassembled)</pre><p>
