fortran版本的eslack,好不容易找到的。里面有程序的索引。主要包括了常用了矩阵计算代码。

1                    EXPLANATION OF COLUMN ENTRIES FOR THE SUMMARY STATISTICS

 -----------------------------------------------------------------------------------------------
 ORDER B.W. TQL2   TQLRAT IMTQL2 IMTQL1    LB      UB    M  IMTQLV   BISECT M1 NO  TRIDIB   BQR 
 -----------------------------------------------------------------------------------------------

 UNDER 'ORDER' IS THE ORDER OF EACH TEST MATRIX.

 UNDER 'B.W.' IS THE HALF BAND WIDTH OF THE MATRIX.

 UNDER 'TQL2   TQLRAT' ARE THREE NUMBERS.  THE FIRST NUMBER, AN INTEGER, IS THE ABSOLUTE SUM OF
 THE ERROR FLAGS RETURNED SEPARATELY FROM  TQL2  AND  TQLRAT.  THE SECOND NUMBER IS THE MEASURE
 OF PERFORMANCE BASED UPON THE RESIDUAL COMPUTED FOR THE  TQL2  PATH.  THE THIRD NUMBER
 MEASURES THE AGREEMENT OF THE EIGENVALUES FROM THE  TQL2  AND  TQLRAT  PATHS.

 UNDER 'IMTQL2 IMTQL1' ARE THREE NUMBERS WITH MEANING LIKE THOSE UNDER  'TQL2   TQLRAT'.       

 UNDER 'LB' AND 'UB' ARE THE INPUT VARIABLES SPECIFYING THE INTERVAL TO  BISECT.               

 UNDER 'M' IS THE NUMBER OF EIGENVALUES DETERMINED BY  BISECT  THAT LIE IN THE
 INTERVAL (LB,UB).

 UNDER EACH OF 'IMTQLV', 'BISECT', 'TRIDIB', AND 'BQR' ARE TWO NUMBERS.  THE FIRST NUMBER,
 AN INTEGER, IS THE ABSOLUTE SUM OF THE ERROR FLAGS RETURNED FROM THE RESPECTIVE PATH.         
 THE SECOND NUMBER IS THE MEASURE OF PERFORMANCE BASED UPON THE RESIDUAL COMPUTED FOR THE PATH.

 UNDER 'M1' AND 'NO' ARE THE VARIABLES SPECIFYING THE LOWER BOUNDARY INDEX AND THE NUMBER      
 OF EIGENVALUES TO  TRIDIB. 

 -1.0  AS THE MEASURE OF PERFORMANCE IS PRINTED IF AN ERROR IN THE CORRESPONDING PATH HAS
 PREVENTED THE COMPUTATION OF THE EIGENVECTORS.

 THE  TQL2    PATH USES THE EISPACK CODES   BANDR-TQL2  ,     
 AS CALLED FROM DRIVER SUBROUTINE  RSB.
 THE  TQLRAT  PATH USES THE EISPACK CODES   BANDR-TQLRAT,     
 AS CALLED FROM DRIVER SUBROUTINE  RSB.
 THE  IMTQL2  PATH USES THE EISPACK CODES   BANDR-IMTQL2.     
 THE  IMTQL1  PATH USES THE EISPACK CODES   BANDR-IMTQL1.     
 THE  IMTQLV  PATH USES THE EISPACK CODES   BANDR-IMTQLV-BANDV. 
 THE  BISECT  PATH USES THE EISPACK CODES   BANDR-BISECT-BANDV. 
 THE  TRIDIB  PATH USES THE EISPACK CODES   BANDR-TRIDIB-BANDV. 
 THE  BQR     PATH USES THE EISPACK CODES   BQR  -BANDV.
