[<ExtensionAttribute>]
static member Where : 
        vector : Vector<'T> * 
        predicate : Func<'T, int, bool> -> Vector<'T>

vector Vector<T>: A vector to filter.
predicate Func<T, Int32, Boolean>: A function to test each element for a condition. The second parameter of the function represents the index of the element.

Vector<T>
A vector that contains the elements from vector that satisfy the condition.

In Visual Basic and C#, you can call this method as an instance method on any object of type Vector<T>. 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).
