Similar to BLAS, the names of Sparse BLAS subprograms have prefixes that determine the data type involved:

s

and

d

for single- and double-precision real;

c

and

z

for single- and double-precision complex respectively.

If a Sparse BLAS routine is an extension of a "dense" one, the subprogram name is formed by appending the suffix

i

(standing for

indexed

) to the name of the corresponding "dense" subprogram. For example, the Sparse BLAS routine

saxpyi

corresponds to the BLAS routine

saxpy

, and the Sparse BLAS function

cdotci

corresponds to the BLAS function

cdotc

.
