OpenBLAS : An optimized BLAS library 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 . Sometimes it is confusing knowing what is a low-level BLAS. #andatleast // Performance varies by use, configuration and other factors. I am trying to statically link a blas library mingw compiled without underscores, with a library that uses underscoring for symbols, so for example the dgemm_ symbol cannot be found during linking. The dgemm routine can perform several calculations. 2) Now a more complex case A(N,M), B(M,N) and C(N,N) with M=5 and N=3 as in the figure, we can also multiply B for A and get a 55 matrix as result.
