Member Function Documentation

gesv()

template<typename TValue >

static int jade::basic_lapack< TValue >::gesv ( layout_type  layout, int  n, int  nrhs, value_type *  a, int  lda, int *  ipiv, value_type *  b, int  ldb  )

static

Computes the solution to the system of linear equations with a square coefficient matrix A and multiple right-hand sides.

Matrices must be in column-major order.

Returns

Zero if successful; otherwise, non-zero.

Parameters

layout	The matrix layout.
n	The number of equations.
nrhs	The number of right-hand sides.
a	The coefficient matrix.
lda	The leading dimension of a.
ipiv	The pivot table.
b	The right-hand sides.
ldb	The leading dimension of b.

potrf()

template<typename TValue >

static int jade::basic_lapack< TValue >::potrf ( layout_type  layout, char  uplo, int  n, value_type *  a, int  lda  )

static

Computes the Cholesky factorization of a symmetric (Hermitian) positive-definite matrix.

Matrices must be in column-major order.

Returns

Zero if successful; otherwise, non-zero.

Parameters

layout	The matrix layout.
uplo	The upper-lower flag.
n	The order of the matrix.
a	The matrix data.
lda	The stride of the matrix.

static

Computes the inverse of a symmetric (Hermitian) positive-definite matrix using the Cholesky factorization.

Matrices must be in column-major order.

Returns

Zero if successful; otherwise, non-zero.

Parameters

layout	The matrix layout.
uplo	The upper-lower flag.
n	The order of the matrix.
a	The matrix data.
lda	The stride of the matrix.
