|Optimization Toolbox Release Notes|
This section introduces the new features and enhancements added in the Optimization Toolbox 2.1.1 since the Optimization Toolbox 2.1 (Release 12.0).
For information about Optimization Toolbox features that are incorporated from Version 2.1, see New Features.
Support for Large Problems that Are Not Well-Scaled
In Version 2.1.1, large-scale finite differencing is improved numerically to handle cases when an optimization problem is not well-scaled. These changes potentially improve the speed and accuracy of results when using the large-scale versions of
fminunc, particularly if the objective function is not well-scaled.
