Hello Everyone,
I have a question, wish learning and need help.
Am I wrong with mine ?
Many thanks in advance.
Best regards,
Loi Le.
You're not wrong, you're just not done.
Use the third row (0 0 0 1) to eliminate the 2/3 in each of the first two rows.
But that row requires that:
0 * X + 0 * Y + 0 * Z = 1
=>Equation 1 & Equation 3 are inconsistent.
Regards
Andy
I agree with you, Andy.

Loi.
Many thanks, Fred. I got it. And I have a related question : "rref( ), rref( ) and symbolics".
In this case, are there the two different output ? ( with applying symbolics )
Many thanks in advance.

Loi Le.
The symbolic evaluation of (the builtin) rref(M) is only expanding M inside the brackets.
The symbolic evaluation of rref(M) is executing rref, then simplyfing the resulting matrix.
