ATLAS is a auto-configured BLAS.

the OP actually needs a BLAS function called "xGEMM", x can be
S, D, Z, depending on data type.  the function does
C := alpha * A * B + beta * C, for general matrices A B C.

LAPACK is a level higher than BLAS, probably doesn't have this
low-level arithmetic.

【 在 netghost (dormdaze) 的大作中提到: 】
: use ATLAS..hehe
: 【 在 thrust (哼哼的多隆猪) 的大作中提到: 】
: : Grab a LAPACK and call it. That should be the state-of-the-art
: : algorithm for linear algebra. You probably could also get
: : pre-compiled binary for your platform too, which are tuned
: : to specific CPUs.
