Types of Objective Functions - MATLAB & Simulink (original) (raw)
Many Optimization Toolbox™ solvers minimize a scalar function of a multidimensional vector. The_objective_ function is the function the solvers attempt to minimize. Several solvers accept vector-valued objective functions, and some solvers use objective functions you specify by vectors or matrices.
