How to use matlab for stepwise regression analysis
1, first open the matlab software.

2. Create a mathematical model you need, as shown in the figure.

3. Draw the root trajectory diagram according to the transfer function.

4. Get the root locus diagram, and calculate the gain of the user-selected point and other closed-loop poles by using rlocfind function.

5, root trajectory analysis, as shown.

6. View its Bode diagram in the interface of stepwise regression analysis tool.
