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. Mathematica-symbolic-toolbox-master.Optimization objective and constraint functions should be defined in terms of a vector, say x.
Mathematica Symbolic Toolbox for MATLAB-Version 1.2 Interfacing, Matlab, Mathlink, code generation, matrices, matrix manipulation, external programs, matlab symbolic toolbox, mathematica symbolic toolbox, Version 2.0 has been updated from: infocenter/MathSource/624/ to work with MATLAB 7.0(R14) and Mathematica 4.2/5.0. Precompiled linux and windows executables are included. The Mathematica Symbolic Toolbox for MATLAB is implemented as a single MEX-file and the source code is included. One can freely mix Mathematica code and MATLAB code without the bother of writing M-files to convert matrices into strings and back. In addition, since MathLink can pass native MATLAB matrices (and not just strings) between Mathematica and MATLAB, it is quick and easy to construct matrices in either system and pass them to the other. It uses the MathLink communication standard supplied with Mathematica and the MEX facility of MATLAB.
