This is because a nonlinearly constrained function needs to include those constraints in its Hessian. The interior-point algorithm requires its Hessian function to be written as a separate function, instead of being part of the objective function. Gradc = jacobian(c,x).' % transpose to put in correct formĬonstraint = matlabFunction(c,gradc, 'vars',) Since fmincon calls the objective function with column vectors, you must be careful to call matlabFunction with column vectors of symbolic variables.

MatlabFunction generates code that depends on the orientation of input vectors. It is much more efficient to use matlabFunction. Therefore you should perform this calculation only once, and generate code, via matlabFunction, to call during execution of the solver.Įvaluating symbolic expressions with the subs function is time-consuming. This means that a symbolic gradient or Hessian has to be placed in the appropriate place in the objective or constraint function file or function handle.Ĭalculating gradients and Hessians symbolically can be time-consuming. Optimization gradients, and sometimes Hessians, are supposed to be calculated within the body of the objective or constraint functions. This requires you to translate between vectors and scalars. However, symbolic variables are scalar or complex-valued, not vector-valued. Need help using MATLAB? Try the MathWorks TAH Resource Kit.Optimization objective and constraint functions should be defined in terms of a vector, say x.

MathWorks Contact: Alyssa Silverman at 50 or How to Obtain MATLAB Note: If you need toolboxes that are not included in the TAH license, contact MathWorks directly to purchase them. The agreement is advantageous to the campus community as it includes MATLAB, Simulink, and 16 other toolboxes that do not come with a normal license. The TAH license covers on-campus and home software use as well as classroom and lab installations for all instructors, eligible staff, researchers, and students. The University of Massachusetts Amherst has a Total Academic Headcount (TAH) license for MATLAB, Simulink and companion toolboxes, which allows us to offer the product at a significantly reduced price. Developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, and Fortran. MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language.
