Range Structure

Members See Also 
Represents a range of indexes.

Namespace: Extreme.Mathematics.LinearAlgebra
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 4.2.11333.0 (4.2.12253.0)

Syntax

C# 
                      public struct Range : IEnumerable<int>, IEnumerable
Visual Basic (Declaration) 
                      Public Structure Range _
	Implements IEnumerable(Of Integer), IEnumerable
Visual C++ 
                      public value class Range : IEnumerable<int>, 
	IEnumerable
F# 
[<SealedAttribute>]
type Range =  
    struct
        interface IEnumerable<int>
        interface IEnumerable
    end

Remarks

Use a Range structure to represent a range of indexes for a vector or matrix. The range runs from StartIndex to EndIndex with increments of Stride.

StartIndex is guaranteed to be the first index in the range. The last index in the range is the largest number of the form StartIndex + kStride that is less than or equal to EndIndex.

The Stride property can also be negative. In this case, the last index in the range is the smallest number of the form StartIndex + kStride that is greater than or equal to EndIndex.

The special range All can be used to represent a range over an entire row, column, or vector, without having to specify the EndIndex explicitly.

Range objects are immutable. Once created, the start index, end index and stride properties cannot be modified. Instead, create a new Range instance.
