Use this code to deploy applications to enterprise and embedded systems.įor more information, return to the Optimization Toolbox page or choose a link below. You can generate portable and readable C/C++ code to solve your optimization problems using MATLAB Coder™. You can compile your applications into apps or libraries with MATLAB Compiler™ and MATLAB Compiler SDK™. You can accelerate numerical gradient calculations using Parallel Computing Toolbox™. Optimization Toolbox works in conjunction with other MATLAB ® tools. After representing your objectives and constraints as MATLAB functions and matrices, the Optimize Live Task helps guide you through this approach by indicating where to select a solver and insert your predefined MATLAB constructs. Here, a quadratic problem with over 40,000 variables is solved in around thirty seconds.Īs an alternative to the problem-based approach, you can use Optimization Toolbox with the solver-based approach. You can quickly solve large and sparse problems with thousands of variables. In addition to solvers for nonlinear, linear, and mixed-integer linear programs, Optimization Toolbox includes specialized solvers for quadratic programs, second-order cone programs, multiobjective, and linear and nonlinear least squares. This includes when the variables represent a yes or no decision, like whether a process is assigned to a processor in this scheduling example. You can add integer constraints to linear problems involving variables which must take on integer values. We can convert this to an optimization expression and use it in the problem to be optimized. This problem’s objective function requires solving an ODE. You can use the problem-based approach even when some functions are not naturally expressed as optimization expressions. options optimset (oldopts,Name,Value) creates a copy of oldopts and modifies the specified parameters using one or more name-value pair arguments. You can define arrays of optimization variables and constraints, and index with numbers or strings, resulting in readable and compact representations of large problems. options optimset (optimfun) creates options with all parameter names and default values relevant to the optimization function optimfun. Optimization problems often have sets of variables or constraints like in this production planning problem. On this problem, the solve function recognizes the problem is nonlinear, applies a nonlinear solver, and uses automatic differentiation for faster gradient evaluations. You can use the problem-based approach to define the optimization variables and their bounds, set the objective, and then solve. This enables you to find optimal designs, minimize risk for financial applications, optimize decision making, and estimate parameters. Optimization Toolbox™ provides solvers for finding a maximum or a minimum of an objective function subject to constraints.
