Functions

func DDOT

func DDOT(n int, x []float64, incx int, y []float64, incy int) float64

func DGEMM

func DGEMM(transa, transb byte, m, n, k int, alpha float64, a []float64,
	lda int, b []float64, ldb int, beta float64, C []float64, ldc int)

func DGEMV

func DGEMV(trans byte, m, n int, alpha float64, a []float64, lda int,
	x []float64, incx int, beta float64, y []float64, incy int)

func DGETRF

func DGETRF(m, n int, a []float64, lda int, ipiv []int, info *int)

func DGETRI

func DGETRI(n int, a []float64, lda int, ipiv []int, work []float64, lwork int,
	info *int)

func DGTSV

func DGTSV(n, nrhs int, dl, d, du, b []float64, ldb int, info *int)

func DSYEV

func DSYEV(jobz, uplo byte, n int, a []float64, lda int, w, work []float64,
	lwork int, info *int)

func SetNumberOfThreads

func SetNumberOfThreads(n uint)

SetNumberOfThreads sets the number of threads used by OpenBLAS.

If your application is already multi-threaded, it will conflict with OpenBLAS multi-threading. Thus, you must set OpenBLAS to use only one thread.
