Opposite of CONCAT()?
CONCAT(matrix,identity(n)) is used to form an intermediate result. A later operation needs to remove identity(n) from the result:
Example: a:=[[1,3],[2,7]]; a:=CONCAT(a,identity(2)); a1:=RREF(a); // The concatenation of identity(2), and a^-1 I was hoping for something similar to these ideas, (to remove identity(n) from a concatenation): // SUPPRESS(a1,identity(2)); // remove(identity(2),a1); // SUB(a1,a1-identity(2)); Treating identity(n) as an object, fails. |
