I can create an identity matrix simulating the union of two points? starting from its coordinates

i really need creatis this array in direction of two points, why? because i wanna detect with another array (a plane of a floor) where the walls looks like ones, if i compare this arrays element by element i will know how many walls are there between this points.

If you know another way to do the same, works too

Question is not clear. Can you show us your data or clearly explain what you want with an example.

we got this:

the plane its an binary array, then i want to know how many walls are there betwens two points, or anoher case there is no walls.

I was thinking create an identity array with the path between two points something like this:

00001

00010

00100

01000

10000

After that compare element by element with the array of the planeand where the susbtract equals 0 its because the path goes through a wall or more.
