public static class BLAS

The BLAS type exposes the following members.

Methods

	Name	Description
	dgemm	Performs : C = alphaop(A)op(B) + beta*C,
	dgemv	Performing matrix-vector product on the form Copy y = alphaop(A)x + betay where op(A) is of size (m x n) (m rows, n columns), alpha and beta are scalars, x and y are vectors. If incx and incy is different from 1, the size of x and y must be at least: Copy (1+(n-1)abs(incx/y)) or (1+(m - 1)*abs(incx/y)) instead of n and m respectively.
	dgesv	Computes the solution to the system of linear equations with a square matrix A and multiple right-hand sides. It uses an LU decomposition with partial pivoting and row interchanges, solving Copy (PLU)*X = B
	dpotrf	Computes the Cholesky factorization of a real symmetric positive-definite matrix. Use dpotrs(BlasUplo, Int32, Int32, Double, Int32, Double, Int32) for solving A*x=B using the factorisation.
	dpotri	Computes the inverse of a real symmetric positive-definite matrix from the Cholesky-factored matrix. Before calling this routine, call dpotrf(BlasUplo, Int32, Double, Int32) to factorize
	dpotrs	Solves a system of linear equations with a Cholesky-factored real symmetric positive-definite matrix. Use dpotrf(BlasUplo, Int32, Double, Int32) for creating the factorisation.
