Identity

Matrix.Identity(n) returns an identity matrix of size $n\times n$.

If the option “Userdata” is set to true (default is false) the output is returned as a pointer rather than a table of tables (compare Matrix.ToUserdata()).

Example.Quanty

print(Matrix.Identity(3))

{ { 1 , 0 , 0 } , 
  { 0 , 1 , 0 } , 
  { 0 , 0 , 1 } }
