OOP matrices (without enabling OOP)

[Buffalo]

So it's possible to use OOP matrices and vectors without actually enabling OOP in meta file according to wiki.

How would following example look with these conditions without OOP enabled? (Curiosity)

local positionBelow = vehicle.position - vehicle.matrix.up

Take a look at the examples.

Wiki source:

This example creates some more matrix utility functions

  
function getMatrixLeft(m) 
    return m[1][1], m[1][2], m[1][3] 
end 
function getMatrixForward(m) 
    return m[2][1], m[2][2], m[2][3] 
end 
function getMatrixUp(m) 
    return m[3][1], m[3][2], m[3][3] 
end 
function getMatrixPosition(m) 
    return m[4][1], m[4][2], m[4][3] 
end 
  
local mat = getElementMatrix(element)  -- Get the matrix 
x,y,z = getMatrixLeft(mat)     -- Get the matrix left direction 
x,y,z = getMatrixForward(mat)  -- Get the matrix forward direction 
x,y,z = getMatrixUp(mat)       -- Get the matrix up direction
