Button Matrix?

Hiya, In an effort to clearly understand.
XO>diode>button>YO+Y1+Y2+Y3
X1>diode>button>" "
X2>diode>" "
X3>diode>" "

They do not go to ground, 16 buttons, 16 diodes, each single X terminal connects with all 4 Y terminals Am I understanding?
TY

No they do not connect to ground and no, they do not connect to all Y lines. An individual button connects to one X and one Y line and it has a diode in series.

Hello,
So then a button circuit path would be:
xo>diode>button>yo x1>diode>button>yo x2>diode>button>y2
xo>diode>button>y1 x1>diode>button>y1 etc..
etc.. etc..

Can the diodes be after the buttons?
TY for assist Guido

Yes, does not matter if the diode is before or behind the switch.

The matrix works as you listed it.
