Iam trynig to solve the following system (mat=coefficient matrix,B=output matrix)
mat =
1 2 6
2 5 14
5 7 24
B=
0
0
0
the expected result is not zeros for sure because this system is linear dependent . And I used mat/B and linsolve(mat,B). However , I have got the answer
ans=
0
0
0
and this warning
Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND =
1.009294e-18.
could any one help me why I got this result and what I should to get the correct answer?
