Get information about the performance of NonlinLeastSquares.
An int
specifying information about convergence.
Value | Meaning |
---|---|
0 | All convergence tests were met. |
1 | Scaled step tolerance was satisfied. The current point may be an approximate local solution, or the algorithm is making very slow progress and is not near a solution, or StepTolerance is too big. |
2 | Scaled actual and predicted reductions in the function are less than or equal to the relative function convergence tolerance RelativeTolerance . |
3 | Iterates appear to be converging to a noncritical point. Incorrect gradient information, a discontinuous function, or stopping tolerances being too tight may be the cause. |
4 | Five consecutive steps with the maximum stepsize have been taken. Either the function is unbounded below, or has a finite asymptote in some direction, or the maximum stepsize is too small. |
