NAME

Math::BLAS::Enum - named constants

SYNOPSIS

    use Math::BLAS::Enum;

DESCRIPTION

Default is to export all constants actually used in the implementation.

Matrix Ordering

The constants in this group can be imported via the :order tag.

BLAS_ROWMAJOR

matrix elements are stored in row-major order (default for Perl)

BLAS_COLMAJOR

matrix elements are stored in column-major order

Matrix Operations

The constants in this group can be imported via the :trans tag.

BLAS_NO_TRANS

operate with the matrix (default)

BLAS_TRANS

operate with the transpose matrix

BLAS_CONJ_TRANS

operate with the conjugate transpose matrix

Triangular Matrices

The constants in this group can be imported via the :uplo tag.

BLAS_UPPER

refer to upper triangular matrix (default)

BLAS_LOWER

refer to lower triangular matrix

The constants in this group can be imported via the :diag tag.

BLAS_NON_UNIT_DIAG

non-unit triangular matrix (default)

BLAS_UNIT_DIAG

unit triangular matrix, that is diagonal matrix elements are assumed to be one

The constants in this group can be imported via the :sort tag.

BLAS_INCREASING_ORDER

sort in increasing order (default)

BLAS_DECREASING_ORDER

sort in decreasing order

Complex Matrix Elements

The constants in this group can be imported via the :conj tag.

BLAS_NO_CONJ
