- where;
-
- ratio - is to a Cray-1 S using FORTRAN coded BLAS.
- c blas & r blas - denote coded and rolled versions of BLAS.
- mflops - millions of floating point operations per second and
- there are (2/3 n**3 + 2 n**2) operations. Each
- operation comprises a multiplication, an addition,
- and associated indexing and load and store functions.
- time - one call to SGEFA and one call to SGESL.
