Select point matrix

vvvv beta question
1

I trying implemt a simple patch to select espceifics points of matrix points.

I create a matrix X*Y with linearSpread and Cross2d. Right.
The first problem is the first point is the of matrix don’t correspondind with the render draw (to control de point I use a quad with transform 2d to see the points).

It’s posible invert this order???

To the other side, using a setSlice and fix binsize to size of matrix I select one line to my matrix points.

But can I selec the colum???

I’m rookie in vvvv. Attach the patch.

Thanks very much

If you want to invert the order for the Cross 2D, you can either use a reverse node for the Y in pin, or make a new linearspread for Y-in and set the width to a NEGATIVE value, like -2.
