Matrix factorization functions are used in many areas and often play an important role in the overall performance of the applications. I cannot find the reference manual for Fortran. The most widely used is the INTEGERI,INFO,IX,IY,J,JX,JY,KX,KY,LENX,LENY #andatleast This is a great write-up. IY=IY+INCY 3) Another possibility is to use operations different from N, for example the transpose T of the hermitian C, for example this two codes are equivalent but the second is faster and use less memory: notice that the LDA and LDB specify the entry dimension of the matrix A and B, therefore in the second case the entry dimension is the first dimension of the original matrices A and B, while in the first example it corresponds to the one of transpose(A) and transpose(B). DOUBLEPRECISIONTEMP INFO=2 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 . Sign up here For example, the Hollerith Constants were not a thing in Fortran 90+, but gfortran compiles them just fine. Results Reproducibility 2.1.5. columns (for column major storage) in memory. oneMKL provides many options for creating code for multiple processors and operating systems, compatible with different compilers and third-party libraries, and with different interfaces. Regarding your first comment, gfortran compiles most of the classic Fortran instructions (usually throws a warning that some stuff has been removed in modern versions, but it compiles). #mustcontainthevectory. IF(ALPHA==ZERO) For other compilers, use the oneMKL Link Line Advisor to generate a command line to compile and link the exercises in this tutorial: http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/. DGEMM Purpose: DGEMM performs one of the matrix-matrix operations C := alpha*op ( A )*op ( B ) + beta*C, where op ( X ) is one of op ( X ) = X or op ( X ) = X**T, alpha and beta are scalars, and A, B and C are matrices, with op ( A ) an m by k matrix, op ( B ) a k by n matrix and C an m by n matrix. #EndofDGEMV.

Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. For example, for the class which represents multiplication subroutines, there are attributes to de-termine which specific multiplication subroutine to be called, attributes to pass the multiplication coefficient, attributes to determine how to reorder the indices in the multiplication component quantities, etc. B.
