Overload List

AbsoluteMaxIndex<T>(ILinearAlgebraOperations<T>, Int32, ReadOnlySpanSlice<T>)

Finds the index of element having max.

AbsoluteMaxIndex<T, TStorage>(ILinearAlgebraOperations<T>, Int32, TStorage) Returns the index of the element of a vector with maximum absolute value.

AbsoluteMaxIndex<T>(ILinearAlgebraOperations<T>, Int32, ReadOnlySpanSlice<T>)

Finds the index of element having max.

C# 
public static int AbsoluteMaxIndex<T>(
	this ILinearAlgebraOperations<T> operations,
