Returns a RefEnumerable<T> that returns the items from a given column in a given 2D T array instance. This extension should be used directly within a foreach loop:

int[,] matrix =
{
    { 1, 2, 3 },
    { 4, 5, 6 },
    { 7, 8, 9 }
};

foreach (ref int number in matrix.GetColumn(1))
{
    // Access the current number by reference here...
}

The compiler will take care of properly setting up the foreach loop with the type returned from this method.

public static Microsoft.Toolkit.HighPerformance.Enumerables.RefEnumerable<T> GetColumn<T> (this T[,] array, int column);

static member GetColumn : 'T[,] * int -> Microsoft.Toolkit.HighPerformance.Enumerables.RefEnumerable<'T>
