[ObsoleteAttribute("Use class FinMath.Statistics.LargestSmallest")]
public static int[] GetTopIndices<TSource>(
	this IEnumerable<TSource> data,
	int count,
	Func<TSource, double> selector,
	bool checkForAbnormals = false
)

Parameters

data
Type: System.Collections.GenericIEnumerableTSource
Reference to a container object.
count
Type: SystemInt32
Numbers of elements to select.
selector
Type: SystemFuncTSource, Double
A transform function to apply to each element.
checkForAbnormals (Optional)
Type: SystemBoolean
Check is array contains NaN values and properly process them.

Type Parameters

TSource
The source data type.

Return Value

Type: Int32
Number of elements stored.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
