yes, multiplying two matrices is commonplace even outside benchmarks ;)
or are you asking about the particular form of the function,
C = alpha*A*B + beta*C? real user codes I've seen don't tend to
use all the features (transpose, scalars alpha, beta or the
inplace/accumulate aspect of C.) but I'm guessing that the serious blas
implementations already special-case no-transpose, alpha==1,
beta==0 and beta==1.
