Thread Subject: lsqr function

I recently installed version 2009a and I have found that the built-in lsqr function does not give the same results as I was previously getting, given the EXACT same inputs. I was previously running version 7.0.1 (R14) SP1. I was wondering if anyone else has had this problem. My solution was to keep using the older version...but perhaps this isn't the best idea.

Hi Angela, can you document what you mean? It can be vague to say that a routine is not returning the same result for the exact same inputs.
