Meaning of prefixes
For the Level 2 BLAS a set of extended-precision routines with the prefixes ES, ED, EC, EZ may also be available.
Level 1 BLAS
In addition to the listed routines there are two further extended-precision dot product routines DQDOTI and DQDOTA.
Level 2 and Level 3 BLAS
Matrix types
Options
The dummy options arguments are declared as CHARACTER*1 and may be passed as character strings.
For real matrices, TRANS_ = `T' and TRANS_ = `C' have the same meaning.
For Hermitian matrices, TRANS_ = `T' is not allowed.
For complex symmetric matrices, TRANS_ = `H' is not allowed.
