Octave Gauss Jordan-CodePudding

I have been trying to do Gauss jordan method in matrices in octave, and I have found diferent ways to call the function, but none works. How can I do that?

A=[1 -2 -1; -1 1 1; 1 1 5]
B=[1; 4; -3]

#format rat

#Transposta = transpose(A)         #Transposta
#Inversa = inv(A)                  #Inversa
#Adjunta = det(A)*inv(A)           #Adjunta se A tiver inversa
determinante = det(A)              #Determinante.
Resultado = Gaussian(A)

CodePudding user response：

Use the rref function...

A = [1 -2 -1; -1 1 1; 1 1 5]
B = [1; 4; -3]
C = [A, B]
[a, b] = rref(C)

Result

a = 1.0000        0        0  -7.1667
         0   1.0000        0  -5.0000
         0        0   1.0000   1.8333
