Question:Error when specifying the optimality tolerance option in LSSolve

Hi everyone,

I have a strange problem with the LSSolve function. I get an error when specifying an optimality tolerance as an option for LSSolve function : "unexpected parameters: optimalitytolerance = 1/1000" (see attached). When I remove the option, the LSSolve function works and returns something. Why ?

This is a problem for me because in my program I automatically generate lots of equations and I need to solve them using the same parameters.  "list1" is an example of a list that makes LSSolve to return an error and therefore it makes my program stop.
Is it possible, when LSSolve returns an Error, to re-run the function without the optimalitytolerance option ?
