1 EXPLANATION OF COLUMN ENTRIES FOR THE SUMMARY STATISTICS ----------------------------------------------------------------------------------------------- ORDER QZIT(T) QZIT(F) ----------------------------------------------------------------------------------------------- UNDER 'ORDER' IS THE ORDER OF EACH TEST MATRIX SYSTEM. UNDER 'QZIT(T) QZIT(F)' ARE TWO NUMBERS AND A KEYWORD. THE FIRST NUMBER, AN INTEGER, IS THE ERROR FLAG RETURNED FROM QZIT. THE SECOND NUMBER IS THE MEASURE OF PERFORMANCE BASED UPON THE RESIDUAL COMPUTED FOR THE QZIT(T) (BOTH EIGENVALUES AND EIGENVECTORS) PATH. THE KEYWORD REPORTS THE DUPLICATION OF COMPUTED EIGENVALUES FROM THE QZIT(T) AND QZIT(F) (EIGENVALUES ONLY) PATHS. 'SAME' MEANS THAT THE EIGENVALUES ARE EXACT DUPLICATES. 'DIFF' MEANS THAT FOR AT LEAST ONE PAIR OF CORRESPONDING EIGENVALUES, THE MEMBERS OF THE PAIR ARE NOT IDENTICAL. 0-1.0 AS THE MEASURE OF PERFORMANCE IS PRINTED IF AN ERROR IN THE PATH HAS PREVENTED THE COMPUTATION OF THE EIGENVALUES AND VECTORS. THE QZIT(T) PATH USES THE EISPACK CODES QZHES-QZIT-QZVAL-QZVEC, AS CALLED FROM DRIVER SUBROUTINE RGG. THE QZIT(F) PATH USES THE EISPACK CODES QZHES-QZIT-QZVAL, AS CALLED FROM DRIVER SUBROUTINE RGG.
