Version 5.1 (R2010b) Optimization Toolbox Software :: Optimization Toolbox Release Notes (Optimization Toolbox™)

The fmincon interior-point and sqp algorithms now attempt to recover from errors in the evaluation of objective functions and nonlinear constraint functions during gradient estimation. The errors include results that are NaN, Inf, or complex. If there is such an error, the finite differencing routines attempt to take different steps.

ktrlink Available for Macintosh 64-Bit Systems

The ktrlink function now works with Macintosh^® 64-bit systems. Therefore, ktrlink works on the same systems as all other Optimization Toolbox functions.

Output Structure Tweaks

All linprog and quadprog algorithms now create a firstorderopt field in the output structure. This field contains the value of the first-order optimality measure at the final point.

All fmincon and quadprog algorithms now create a constrviolation field in the output structure. This field contains the largest value of the constraint functions at the final point: bounds, linear constraints, and nonlinear constraints. (Some algorithms return the larger of the constraint functions and 0.) See Writing Constraints.
