The final asnwer should be 200, 1400 and 600. But why there is decimal in my final matlab answer? Did I left something?
A = [ 1 1 1 ; 0.06 0.08 0.09 ; 3 0 -1]
A =1.0000 1.0000 1.0000
0.0600 0.0800 0.0900
3.0000 0 -1.0000
>> B= [ 2200 ; 178 ; 0]
B = 2200
178
0
>> AB = [ A B ]
AB =1.0e+03 *
0.0010 0.0010 0.0010 2.2000
0.0001 0.0001 0.0001 0.1780
0.0030 0 -0.0010 0
>> rref(AB)
ans =1.0e+03 *
0.0010 0 0 0.2000
0 0.0010 0 1.4000
0 0 0.0010 0.6000
