The case where no solution exists isn't treated separately, as that would require one to use an arbitrary threshold. If you want to check whether a solution exists, just call this function to get a solution and then compute the margin of error, or use MatrixBase::isApprox() directly, for instance like this: \code bool = a_solution_exists = (A*result).isApprox(b, precision); \endcode As long as the input matrices have finite numeric coefficients (no \c inf or \c nan values), the result will also have finite numeric coefficients, there is no risk of getting \nan values if no solution exists.""
