solve Ax=b by singular value decomposition

After I've got U,S,V by [U,S,V] = svd(A), how do I get x?

Is it x = (V*(S^(-1)*U')*b?

Hi Jiapeng, why not run a test case and see what happens?

[Steven Lord]

Is there a particular reason you're using svd rather than simply using the \ operator?

[Torsten]

Is it x = (V*(S^(-1)*U')*b?

No, only if S has all singular values not equal to 0.
