public static Single[] MaxAbsoluteNormalization(Single[] vector)

Parameters

vector Single[]

Returns

Single[]
The same array

MaxAbsoluteNormalization(Span<Single>)

In-place multiple every element by 32760 and divide every element in the span by the max absolute value in the span

1
public static Span<float> MaxAbsoluteNormalization(Span<float> vector)

Parameters

vector Span<Single>

Returns

Span<Single>
The same span

TaxicabNormalization(Single[])

In-place divide every element in the array by the sum of absolute values in the array
