Extreme Optimization Numerical Libraries for .NET Professional
Gets or sets the elements of a column of the matrix that meet the specified condition.

Namespace:  Extreme.Mathematics
Assembly:  Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.1
Syntax

C#
VB
C++
F#
Copy
public Vector<T> this[
	Func<T, bool> condition,
	int column
] { get; set; }
Public Default Property Item ( 
	condition As Func(Of T, Boolean),
	column As Integer
) As Vector(Of T)
	Get
	Set
public:
property Vector<T>^ default[Func<T, bool>^ condition, int column] {
	Vector<T>^ get (Func<T, bool>^ condition, int column);
	void set (Func<T, bool>^ condition, int column, Vector<T>^ value);
}
member Item : Vector<'T> with get, set

Parameters

condition
Type: SystemFuncT, Boolean
A delegate that represents a predicate that specifies the condition to test.
column
Type: SystemInt32
The zero-based index of the column.

Property Value

Type: VectorT
A vector.
Exceptions

ExceptionCondition
ArgumentNullExceptionvalue is
DimensionMismatchException The length of value does not equal the number of elements for which condition is .
Remarks

This property allows you to directly retrieve or set the elements of a column of this matrix.

Getting the value of this property returns a new vector with the elements for which condition is . Setting the value of this property sets the selected elements to the values in the vector that is provided.
