When you have the Parallel Computing Toolbox™ software, you can use parallel computing to speed up parameter estimation and response optimization. When you use parallel computing, the software distributes the independent simulations on multiple MATLAB® sessions. Thus, the simulations run in parallel which reduces the optimization time.
Using parallel computing may reduce the optimization time in the following cases:
The model contains a large number of parameters to optimize, and the Gradient descent or Nonlinear least squares method is selected.
ThePattern search method is selected as the optimization method.
The model contains a large number of uncertain parameters and uncertain parameter values.
The model is complex and takes a long time to simulate.
