The next two letters in the naming convention indicate the form of the matrix,
as presented in Table 3-2.
Table 3-2 Extended BLAS Naming Convention—Matrix Form
Table 3-3 lists the final one, two, or three characters in the naming convention,
indicating the computation of a particular subroutine.

For example, SGBMV multiplies a vector (MV) by a general band matrix (GB)
using the single precision REAL data type (S). ZTRSM solves a system of linear
equations with one triangular coefficient matrix and a matrix of right-hand
sides, using the double precision COMPLEX data type.
