Functions

func Inverse

func Inverse(ctx context.Context, m [][]float64) ([][]float64, error)

Inverse performs matrix inversion.

func IsRegular

func IsRegular(x [][]float64) bool

IsRegular checks if a 2D slice is a non-nil, regular matrix.

func Multiply

func Multiply(ctx context.Context, x [][]float64, y [][]float64) ([][]float64, error)

Multiply produces matrix product z=xy.

func MultiplyByVector

func MultiplyByVector(ctx context.Context, x [][]float64, y []float64) ([]float64, error)

MultiplyByVector multiples a given matrix by a given vector.

func Transpose

func Transpose(ctx context.Context, x [][]float64) ([][]float64, error)

Transpose performs a matrix transposition.
