Module blas 

BLAS (Basic Linear Algebra Subprograms) interface

This module provides interfaces to BLAS functions.

The BLAS (Basic Linear Algebra Subprograms) are routines that provide standard building blocks for performing basic vector and matrix operations.

Functions

asum

Computes the sum of absolute values of a vector (Level 1 BLAS operation).

axpy

Performs a scaled vector addition (Level 1 BLAS operation): y = alpha*x + y

dot

Computes the dot product of two vectors (Level 1 BLAS operation).

gemm

Performs matrix-matrix multiplication (Level 3 BLAS operation): C = alphaAB + beta*C

gemv

Performs matrix-vector multiplication (Level 2 BLAS operation): y = alphaAx + beta*y

iamax

Finds the index of the element with the largest absolute value (Level 1 BLAS operation).

nrm2

Computes the 2-norm (Euclidean norm) of a vector (Level 1 BLAS operation).
