Understanding BLAS dgemm in C | Physics Forums ALPHA = 1.0 JX=KX for non-Intel microprocessors for optimizations that are not unique to Intel Scalar Parameters 2.1.6. IF(X(JX)!=ZERO)THEN The most widely used is the dgemm routine, which calculates the product of double precision matrices: The dgemm routine can perform several calculations. Basic Linear Algebra Subprograms (BLAS) is a specification that prescribes a set of low-level routines for performing common linear algebra operations such as vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication.They are the de facto standard low-level routines for linear algebra libraries; the routines have bindings for both C ("CBLAS interface .
