( Let me know if I broke anything. I double checked. We should be fine but )
( please let me know if concerns/problems. )
1) The comments in ICMAX1 (resp. IZMAX1) were not correct. The comments read:
"ICMAX1 finds the index of the element whose real part has maximum absolute
value." It should have read: "ICMAX1 finds the index of the first vector
element of maximum absolute value." This is corrected. The problem was reported
Eloy Romero Alcalde from the SLEPc team, Universitat Politècnica de València
and confirmed by Nick Higham, Sven Hammarling and Julien Langou.
2) The routine ICAMAX (resp. IZAMAX) from the BLAS evolved without ICMAX1
(resp. IZMAX1). Reconcialated both version. So essentially took the ICAMAX
currently in the BLAS and changed it appropriately for an ICMAX1.
3) Remove the use of statement function in ICMAX1 (resp. IZMAX1). Now obsolete
in FORTRAN.
4) Change comments in BLAS routines: SCABS1, DCABS1, ICAMAX, IZAMAX, SCASUM,
and DZASUM. Remove the use of "absolute value of a complex number" for the
quantity "| Re(.) | + | Im(.) |". For example:
before
DCABS1 computes absolute value of a double complex number
after
DCABS1 computes |Re(.)| + |Im(.)| of a double complex number
