Yeah, I used the backslash in my code.

I'm linearizing a nonlinear inversion problem and solving A*m=b in a least squares sense, where A is the jacobian matrix. 

Backslash seems provide no help.  I still get a warning that the matrix is badly scaled or nearly singular and sometimes it gives rise to NaNs.
