Functions

func ArgMax 

func ArgMax(xs []float64) int

ArgMax is the index of the largest element

func Clamp 

func Clamp(x, min, max float64) float64

func Dot 

func Dot(xx, yy []float64) float64

Dot product

func ExtractArray 

func ExtractArray(t *vm.Table) (any, error)

extractArray reads the sequential 1..n portion of t into a typed Go slice. The element type is inferred from the values: all-strings → []string, all-ints → []int64, mixed int/float (or all-float) → []float64. Mixing strings with numbers, or any other value type, is a hard error — sorting heterogeneous values has no obvious total order so we'd rather fail loudly than guess.

func MaxOf 

func MaxOf(xx []float64) float64

maxOf returns the largest element. Callers must guarantee a non-empty slice.

func Maxf 

func Maxf(xs []float64) float64

func Meanf 

func Meanf(xs []float64) float64

func MinOf 

func MinOf(xx []float64) float64

minOf returns the smallest element. Callers must guarantee a non-empty slice.

func Minf 

func Minf(xs []float64) float64

func Normalize 

func Normalize(xs []float64)

Normalize scales to (0, 1)

func Round 

func Round(x float64) float64

Round to nearest integer

func Sgn 

func Sgn(x float64) float64

Sgn is signum

func Softmax 

func Softmax(xx []float64) []float64

softmax converts a slice of scores into a probability distribution. The max is subtracted before exponentiating for numerical stability (so large inputs don't overflow Exp). An empty input yields an empty output rather than dividing by a zero sum.

func Stddevf 

func Stddevf(xs []float64) float64

func Sumf 

func Sumf(xs []float64) float64

func Variancef 

func Variancef(xs []float64) float64

func WriteBack 

func WriteBack[T any](t *vm.Table, values []T)

writeBack copies a sorted Go slice into the 1..n positions of t, matching Lua's in-place sort semantics. Indices beyond n are left untouched — callers shouldn't be putting holes in an array part anyway.
