The description applies to the trust-region reflective.

It is minimizing the function 5x-ln (x) with the starting point 0.1 and constraint 0

The value of the step size tolerance but constraints are not
FMINCON MATLAB EXAMPLE CODE
When I run your code with a profiler, it takes 460 seconds, where 396 seconds are spent for interp1, 2808319 calls, that is 141 ms per 1000 calls. Fmincon stopped because the size of the current step is less than Examples of Constrained Minimization using FMINCON FMINCONis a function included in MATLAB's Optimization Toolbox which seeks the minimizer of a scalar function of multiple variables, within a region specified by linear constraints and bounds. 1 Answer Sorted by: 1 Surprisingly, but the problem is not in load.
