Ways to Speed up Frequency Response Estimation

The most time consuming operation during frequency response estimation is the

simulation of your Simulink model. You can try to speed up the estimation using any of

the following ways:

• Reducing simulation stop time


• Specifying accelerator mode


• Using parallel computing

Reducing Simulation Stop Time

The time it takes to perform frequency response estimation depends on the simulation

stop time.

To obtain the simulation stop time, in the Linear Analysis tool, in the Linear Analysis

Workspace, select the input signal. The simulation time will be displayed in the Variable

Preview.

To obtain the simulation stop time from the input signal using MATLAB Code:
