Gets the indices of the extrema (minima and maxima) of the signal.

Namespace: Altaxo.Science.Signals
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3448.0 (4.8.3448.0)
Syntax
C#
Copy
public static (List<int> IndicesOfMinima, List<int> IndicesOfMaxima) GetIndicesOfExtrema(
	IReadOnlyList<double> y,
	List<int>? indicesOfMinima = null,
	List<int>? indicesOfMaxima = null
)

Parameters

y  IReadOnlyListDouble
The y-values of the signal.
indicesOfMinima  ListInt32  (Optional)
A list that can be reused as return value for the indices of minima. If , a new list for the indices of minima will be allocated.
indicesOfMaxima  ListInt32  (Optional)
A list that can be reused as return value for the indices of maxima. If , a new list for the indices of maxima will be allocated.

Return Value

ValueTupleListInt32, ListInt32
A tuple containing the list of indices of the minima and maxima of the signal. Note that the start and end of the signal cannot be a minimum or maximum.
