Functions ¶
func Abs ¶
func Abs[T types.RealNumbers](v []T) (res []T, err error)
func Add ¶
func Add[T types.RealNumbers](v1, v2 []T) ([]T, error)
func Cast ¶
func Cast[I types.RealNumbers, O types.RealNumbers](in []I) (out []O, err error)
func Compare ¶
func Compare[T types.RealNumbers](v1, v2 []T) int
Compare returns an integer comparing two arrays/vectors lexicographically. TODO: this function might not be correct. we need to compare using tolerance for float values. TODO: need to check if we need len(v1)==len(v2) check.
func CosineDistance ¶
func CosineDistance[T types.RealNumbers](v1, v2 []T) (float64, error)
func CosineSimilarity ¶
func CosineSimilarity[T types.RealNumbers](v1, v2 []T) (float64, error)
func Divide ¶
func Divide[T types.RealNumbers](v1, v2 []T) ([]T, error)
func InnerProduct ¶
func InnerProduct[T types.RealNumbers](v1, v2 []T) (float64, error)
func L1Norm ¶
func L1Norm[T types.RealNumbers](v []T) (float64, error)
L1Norm returns l1 distance to origin.
func L2Distance ¶
func L2Distance[T types.RealNumbers](v1, v2 []T) (float64, error)
func L2Norm ¶
func L2Norm[T types.RealNumbers](v []T) (float64, error)
L2Norm returns l2 distance to origin.
func Multiply ¶
func Multiply[T types.RealNumbers](v1, v2 []T) ([]T, error)
func NormalizeGonumVector ¶ added in v1.1.1
NormalizeGonumVector normalizes a vector in place. Note that this function is used by the kmeans algorithm. Here, if we get a zero vector, we do not normalize it and return it directly. This is because the zero vector is a valid vector in the kmeans algorithm.
func NormalizeGonumVectors ¶ added in v1.1.1
func NormalizeL2 ¶
func NormalizeL2[T types.RealNumbers](v1 []T) ([]T, error)
func ScalarOp ¶ added in v1.2.0
func ScalarOp[T types.RealNumbers](v []T, operation string, scalar float64) ([]T, error)
func SubArrayFromLeft ¶ added in v1.2.0
func SubArrayFromLeft[T types.RealNumbers](s []T, offset int64) []T
SubArrayFromLeft Slice from left to right, starting from 0
func SubArrayFromLeftWithLength ¶ added in v1.2.0
func SubArrayFromLeftWithLength[T types.RealNumbers](s []T, offset int64, length int64) []T
SubArrayFromLeftWithLength Cut the slice with length from left to right, starting from 0
func SubArrayFromRight ¶ added in v1.2.0
func SubArrayFromRight[T types.RealNumbers](s []T, offset int64) []T
SubArrayFromRight Cut slices from right to left, starting from 1
func SubArrayFromRightWithLength ¶ added in v1.2.0
func SubArrayFromRightWithLength[T types.RealNumbers](s []T, offset int64, length int64) []T

func Subtract ¶
func Subtract[T types.RealNumbers](v1, v2 []T) ([]T, error)
func ToGonumVector ¶
func ToGonumVector[T types.RealNumbers](arr1 []T) *mat.VecDense
func ToGonumVectors ¶
func ToGonumVectors[T types.RealNumbers](arrays ...[]T) (res []*mat.VecDense, err error)
