| 3 * optimization/__fdjac__.m: Pass in fvec to save one evaluation. | |
| 4 * optimization/fsolve.m: Avoid redundant reevaluation when using | |
| 5 FD jacobians. Document how it can be done with user jacobians. Make | |
| 6 first iteration special and call outputfcn after it. Skip updates | |
| 7 unless two successful iterations have occured. | |
| 8 * optimization/__dogleg__.m: Add missing alpha in the zero-gradient | |
| 9 case. | |
